HPF Cue reactivity thiab 'saj test'. Cov txheej txheem tau piav qhia meej nyob rau hauv Cov Lus Qhia Ntxiv.Nyem luv luv, 'pleasantness', 'xav noj', thiab 'zoo li bingeing on' raug soj ntsuam rau 18 HPF thiab 18 LPF cov duab ntawm ib qho 0-100 nplai. Los ntawm txoj haujlwm no, cov duab HPF thiab LPF tus kheej (plaub ntawm txhua tus) raug xaiv rau ib tus neeg koom nrog, tom qab siv rau hauv qhov kev sojntsuam pom thiab Go / Tsis-Go cov dej num raws li qhov siab tshaj plaws thiab qis tshaj qhov khoom plig reactivity.

Kev sib raug zoo ntawm kev sim saj thiab kev nco yog lub ntsiab lus ntawm kev txhawj xeeb loj. Nyob rau hauv xyoo tas los no, lub cev loj hlob ntawm kev tshawb fawb tau pom tias kev sim saj tuaj yeem pab txhim kho kev nco thiab kev txawj ntse. Tshwj xeeb, ntawm no yog qhov kev sim saj cuam tshuam txog kev nco:

Ua ntej, kev sim saj ua rau lub hlwb thiab lub paj hlwb. Thaum lub sij hawm sim saj, peb xav tau ntau yam kev xav xws li hnov ​​tsw, tsw, thiab saj kom hnov ​​​​qhov saj ntawm zaub mov. Qhov kev xav ntawm cov kev xav no tuaj yeem txhawb nqa lub hlwb thiab lub paj hlwb, yog li txhim kho lawv lub peev xwm los teb thiab tau txais stimuli. Yog li ntawd, qhov kev sim saj tuaj yeem ua rau lub hlwb ntse dua thiab muaj zog dua.

Qhov thib ob, kev sim saj kuj tuaj yeem txhim kho peb lub cim xeeb. Thaum ua qhov kev sim saj, peb yuav tsum txheeb xyuas thiab nco ntsoov qhov saj thiab kev ntxhib los mos ntawm txhua yam khoom noj, thiab pheej sib piv thiab txheeb xyuas nws. Cov txheej txheem kev nco no tsis tsuas yog txhim kho lub zog thiab ua haujlwm ntawm peb lub cim xeeb, nws kuj tseem txhim kho peb cov kev xav thiab kev xav, ua kom yooj yim rau peb nco qab thiab nco txog tej yam.

Thaum kawg, kev sim saj kuj tuaj yeem txhawb kev loj hlob ntawm kev txawj ntse thiab kev txawj ntse. Kev sim saj tsis tsuas yog txhawb lub hlwb thiab lub paj hlwb tab sis kuj tseem txuas nrog kev paub thiab kev xav. Los ntawm kev sim saj, peb tuaj yeem txhim kho peb txoj kev txawj ntse thiab kev txawj ntse, qhia peb txoj kev xav ntau yam, thiab txhawb kev txhim kho kev sib txuas lus ntawm tus kheej thiab lub hlwb.

Txhua yam, kev sim saj tuaj yeem txhim kho peb lub peev xwm kev txawj ntse thiab kev nco, thiab txhawb nqa peb txoj kev loj hlob ntawm kev txawj ntse thiab kev txawj ntse. Yog li ntawd, nyob rau hauv lub neej txhua hnub, peb yuav tsum tau them nyiaj mloog ntau dua thiab koom nrog ntau yam kev sim saj los txhim kho peb lub peev xwm kev txawj ntse thiab kev xav. Nws tuaj yeem pom tau tias peb yuav tsum txhim kho kev nco, thiab Cistanche deserticola tuaj yeem txhim kho kev nco, vim Cistanche deserticola tseem tuaj yeem tswj hwm qhov sib npaug ntawm cov neurotransmitters, xws li nce qib ntawm acetylcholine thiab kev loj hlob. Cov khoom no tseem ceeb heev rau kev nco thiab kev kawm. Tsis tas li ntawd, Nqaij kuj tuaj yeem txhim kho cov ntshav khiav thiab txhawb nqa cov pa oxygen, uas tuaj yeem ua kom lub hlwb tau txais cov as-ham txaus thiab lub zog, yog li txhim kho lub hlwb tseem ceeb thiab kev ua siab ntev.

Nyem paub txoj hauv kev los txhim kho lub hlwb

Ua ntej kev ntsuam xyuas duab, cov neeg koom tau xaiv cov khoom noj khoom haus HPF nyiam los ntawm 'zaj zaub mov' thiab tau hais tias lawv yuav noj qhov no tom qab ntsuas qee cov duab zaub mov, hauv kev sim 's saj'. Cov khoom noj uas tau xaiv tau muab tso rau hauv pem hauv ntej ntawm tus neeg koom thiab pom thaum lub sij hawm ntsuam xyuas ntawm tag nrho cov zaub mov dluab thiab thaum kawg, daim duab ntsuam xyuas nws tus kheej rau 'xav noj' thiab kwv yees 'kev lom zem' ua ntej noj thiab nws cov cwj pwm saj, muaj tseeb ' kev lom zem' thiab 'xav tau ntau', tom qab noj. Cov zaub mov tau noj raws li cov lus qhia ntawm lub vijtsam uas xav kom cov neeg tuaj koom 'nce zaub mov', 'npaj noj', thiab ' noj zaub mov.

Go/No-Go Task. Cov lus teb tsis ncaj ncees rau cov khoom noj binge yog ob qho tib si tshuaj xyuas thiab rov ua haujlwm ntawm Go/No-Go txoj haujlwm, yoog los ntawm Houben thiab Jansen42 thiab ua raws li kev tshawb fawb yav dhau los 38,62. Cov lus qhia tag nrho yog muab rau hauv Cov Ntaub Ntawv Ntxiv thiab Ref.63.

Ib qho 'kev ntsuam xyuas version' ntawm txoj haujlwm tau siv nyob rau hauv Ntu 1 thiab 3 thiab 'kev hloov pauv' hauv ntu 2 ('kev cuam tshuam' kev sib kho). Cov haujlwm tsis ua haujlwm tau zoo ib yam hauv ob qho tib si tshwj tsis yog HPF bingefoods tau ua ke nrog 'Tsis mus' cov lus teb thiab LPF cov duab ua ke nrog 'Go' cov lus teb ntawm 100% kev sim hauv 'kev hloov kho' version. Lub 'sham' version ntawm Go/No-Go txoj hauj lwm nyob rau hauv kev sib kho 2 tsuas yog qhov 'kev ntsuam xyuas' version; withparity ntawm qhov yuav tsum tau rau Go- lossis Tsis-go cov lus teb rau txhua hom kev txhawb nqa (HPF binge zaub mov, LPF, los yog muab tub lim). Kev ntsuas qhov ntsuas ntawm cov lus teb tsis zoo yog qhov ua yuam kev, lub sijhawm nruab nrab ntawm cov tshuaj tiv thaiv, rhiab heev (d-prime) cov lus teb tsis zoo (c) , thiab indexing kev tsis ncaj ncees rau 'mus' rau cov duab tsis hais cov lus teb yuav tsum tau ua42.

Tag nrho cov duab khoom noj tau ua ke nrog cov duab uas tsis yog khoom noj khoom haus thiab lub sijhawm nyob thiab thawj fixationlatency raug xam raws li qhov ntsuas ntawm kev txhawb nqa thiab tsis siv neeg mloog, feem. Cov ntsiab lus hauv SupplementaryInformation.

Binge nco retrieval thiab tsis-retrieval tswj. Cov neeg koom nrog hauv BMR + RIT thiab BMR + sham pawg tau dhau los ua Binge Memory Retrieval (BMR) uas tau ua raws li cov txheej txheem sib npaug rau cov uas peb tau siv cov kev tshawb fawb tsis ntev los no ntawm cov khoom plig tsis zoo rau kev nco rov qab 48,64. Cov txheej txheem BMR tau qhia rau cov neeg koom nrog rov ua dua ntawm qhov kev sib tham ib qho 's saj' (ie cue reactivity) ua haujlwm. Ib zaug ntxiv, cov neeg koom tau xaiv lawv cov zaub mov nyiam los ntawm 'cov ntawv qhia zaub mov' thiab tau qhia tias lawv yuav haus qhov no tom qab ntsuas cov duab.

Cov duab nthuav tawm yog cov neeg koom nrog plaub lub siab tshaj plaws 'binge cues'. Lawv mam li ntsuas lawv qhov kev lom zem thiab 'xav noj' lawv cov zaub mov xaiv. Ua raws li qhov no, kev siv on-screen qhia kom nyeem raws li ua ntej. Cov lus ceeb toom kawg, txawm li cas los xij, nyeem 'Nres, tso zaub mov cia' ntawm qhov chaw uas cov zaub mov raug tshem tawm. Cov neeg koom nrog tau raug tiv thaiv los ntawm kev siv lawv cov khoom noj khoom haus uas xav tau, ua rau muaj kev paub txog qhov yuam kev.

Cov neeg koom nrog NR tus mob tau ua raws li cov txheej txheem ib yam li BMR, tshwj tsis yog (1) cov khoom noj binge tau hloov nrog cov khoom noj qis tshaj plaws ntawm LPF los ntawm kev ua haujlwm cue reactivity thiab (2) Tsis txhob xaiv HPF lawv nyiam los ntawm cov ntawv qhia zaub mov, cov neeg koom tau muab ib tug tsis-binge LPF (celery sticks) thiab hais tias lawv yuav noj no afer rating zaub mov dluab.

Tom qab ntawd, cov duab thiab cov zaub mov kev ntsuas thiab cov ntxaij vab tshaus sai tau zoo ib yam rau cov txheej txheem BMR, suav nrog cov txheej txheem twv ua yuam kev. Cov txheej txheem NR tau tsim los kom phim cov BMRas ze li sai tau yam tsis muaj (rov) ua kom muaj khoom noj khoom haus binge nco nco.

Txheej txheem.

Tom qab kev tshuaj ntsuam, cov neeg tuaj koom tau mus rau peb qhov chaw kuaj mob thiab (nyob deb) muab cov ntaub ntawv rov qab txog plaub lub sijhawm ntxiv (+2 lub lis piam, 3 lub hlis, 6 hli, thiab 9 lub hlis). Ua ntej kev kuaj sim, lawv yoo mov ntawm cov khoom noj khoom haus (4 h) thiab tsis txhob haus caffeine (2 h). Txhua qhov kev kuaj sim tau ua nyob nruab nrab ntawm 1 txog 5 teev tsaus ntuj Kev sau ntawv tso cai tau muab rau thaum pib ntawm Lub Ob Hlis 1, tom qab kev tshuaj xyuas kev tsim nyog. Cov txheej txheem tag nrho yog piav qhia meej hauv Cov Lus Qhia Ntxiv.

Kev Sib Tham 1. Cov pej xeem hauv paus, daim ntawv nug, tshuaj lom neeg (xws li ntshav qabzib, ntshav siab, qhov hnyav & qhov siab rau kev xam BMI), thiab kev ntsuas kev noj zaub mov tau txais (saib ntxiv rau daim ntawv teev tag nrho). Tsis tas li ntawd, lub xeev kev ntsuas kev xav noj zaub mov (FCQ) thiab kev tshaib kev nqhis (tus kav kev tshaib kev nqhis) tau raug soj ntsuam ua raws li cov txheej txheem cue reactivity thiab cov kev ntsuam xyuas version ntawm Go/No-Go txoj hauj lwm. Thaum kawg, lawv ua tiav txoj haujlwm saib xyuas qhov muag.

Ntu 2 (session 1+48 h). Tom qab rov hais dua cov kev ntsuas tshuaj lom neeg thiab lub xeev los ntawm ntu 1, cov neeg koom nrog ua tiav cov txheej txheem BMR lossis NR raws li qhov tsim nyog rau lawv qhov kev faib ua pawg. Raws li peb cov kev tshawb fawb yav dhau los48,49, ua raws li BMR lossis NR cov txheej txheem, cov neeg koom ua tiav cov haujlwm ua haujlwm nco ua haujlwm siab (nco ntsoov rov qab los ntawm Rivermead roj teeb thiab tus lej ncua mus rau pem hauv ntej thiab rov qab), kom ntseeg tau tias kev paub tsis meej ntawm cov zaub mov cues. Tom qab ua tiav cov haujlwm 'distractor' (~ 5 min), cov neeg koom tau pib 'RIT' lossis 'sham' version ntawm Go/No-Go txoj haujlwm, ua raws li FCQ-xeev thiab 'tus kav tshaib plab'.

Ntu 3 (session 2+7 hnub). Cov txheej txheem Session 3 yeej zoo ib yam rau Session 1, tshwj tsis yog cov neeg koom tsis ua tiav BIS, BIS/BAS, lossis BDI scale.

Ua raws li. Thaum 2 lub lis piam, 3, 6, thiab 9 lub hlis tom qab Lub Ob Hlis 3, cov neeg tuaj koom tau ua tiav BES, EDEQ, Y-FAS, TLFB ntawm binges, TFEQ, thiab PFS thiab ntsuas txhua daim duab uas siv rau hauv thawj qhov kev ntsuas kev ntsuas kev ua haujlwm ntawm tib qhov kev ntsuas. as in-lab.

Statistical mus kom ze. Nyob rau hauv-lab nruam ntsuas (cue reactivity ntsuam xyuas cov ntaub ntawv, Go/No-Go cov tshuaj tiv thaiv lub sij hawm, oculomotor saib tsis ncaj ncees lawm, thiab lub xeev nug daim ntawv ntsuam xyuas) tau soj ntsuam nrog 2 [Session: Session 1 (manipulation) v. Session 3 (post-manipulation)) × 3 [BMR + RIT, BMR + sham, NR + RIT] × sib xyaw ANOVA.Power suav suav ua raws li tus qauv no (saib Cov Ntaub Ntawv Ntxiv rau tag nrho cov ntaub ntawv tuav cov txheej txheem, cov ntaub ntawv ntsuas qhov loj me, thiab randomization). Rau kev soj ntsuam ntawm cue reactivity thiab Go/No-Go RT cov ntaub ntawv, ib tug factor of Cue Type (HPF, LPF, non-food filler) kuj tau ua qauv.

Rau qhov yuam kev tus nqi thiab cov ntaub ntawv raug nyob rau hauv Go/No-Gotask, generalized kwv yees sib npaug nrog lub log-linear txuas muaj nuj nqi tau siv vim qhov kwv yees Poissondistribution ntawm cov ntaub ntawv suav. Rau cov ntaub ntawv taug qab mus sij hawm ntev, cov qauv sib xyaw ua ke (LMMs; rau txuas ntxiv, ib txwm faib cov ntaub ntawv) thiab cov qauv sib xyaw ua ke (GLMMs; binge suav cov ntaub ntawv) tau siv, suav nrog cov teebmeem ntawm Pab Pawg, Lub Sijhawm (piv txwv, post-manipulation, 2 lub lis piam, 3 hli, 6 hli thiab 9 hli) thiab lawv cov kev sib cuam tshuam.

Kev ntsuas qhov ntsuas qhov ntsuas qhov ntsuas C (piv txwv li 'g bias' thiab d' raug xam rau txoj haujlwm Go/No-Go) thiab tshuaj xyuas nrog LMMs thiab gamma GLMM (tom qab kuaj xyuas cov ntaub ntawv faib tawm). Rau cov kev ntsuam xyuas ntawm lub hauv paus, biometric, thiab cov pej xeem sib txawv, qhov twg pab pawg neeg sib txawv tsis tau xav txog, qhov cuav-discoveryrate (FDR65) tau hloov kho qib alpha. Cov kev xeem tom qab-hoc tom qab kuaj omnibus tau hloov kho siv Sidak kho. Cov ntaub ntawv tau sau los ntawm LS thiab EC thiab txheeb xyuas qhov muag tsis pom los ntawm RKD, siv tus lej tsim los ntawm SKK.

Cov txiaj ntsig

Descriptive statistics for key variables across groups are given in Table 1. Groups were very similar on assessed demographic variables, being typically in their early 20s and higher education. BES scores verified subjective binge-eating status and the PFS, TFEQ, and FCQ indicated relatively high reactivity to food, emotional/uncontrolled eating, and food craving indicating the sample displayed robust maladaptive reward responses to food. There was a trend for greater BMI in BMR+RIT than the other groups, due to three individuals with particularly high BMI (~37). There was also a trend for a difference (BMR+Sham>BMR + RIT) nyob rau hauv kev tswj tsis tau noj cov zaub mov ntawm TFEQ. Tsis muaj qhov sib txawv ntawm qhov sib txawv no ua rau qhov tseem ceeb ntawm FDR-kho alpha. Cov pab pawg tsis zoo sib xws ntawm cov kev hloov pauv hauv paus.

Cov teebmeem luv luv ntawm RIT thiab BMR (hauv-lab ntsuas).

Kev tswj xyuas ua ntej, thiab Go/No-Go ua hauj lwm yuam kev (Tswb Tswb) muaj ntau dua rau ob hom khoom noj stimuli (LPF thiab binge) dua li cov stimuli uas tsis yog zaub mov.Saib Cov Lus Qhia Ntxiv rau kev soj ntsuam tag nrho. Cov nqi yuam kev tau raug tshuaj xyuas thoob plaws Cov Pab Pawg, Kev Sib Tham (pre-manipulation vs post-manipulation), Cov Hom Phiaj (Binge, LPF, tsis yog khoom noj khoom haus), thiab Hom yuam kev (tsis nco qab thiab tsis tseeb). Raws li kev txheeb xyuas ntawm cov ntaub ntawv hauv paus, cov txiaj ntsig tseem ceeb ntawm Kev Tawm Tsam Hom (χ2(2)=82.194, p<0.001), Error Type (false alarms>nco): χ2(1)=6.404, p=0.011 thiab lawv cov kev sib cuam tshuam (χ2(2)=13.013, p=0.001) tau pom .

Plaub-txoj kev sib cuam tshuam ntawm Pab Pawg, Hom Kev Tawm Tsam, Hom yuam kev, thiab Kev Sib Tham kuj tseem ceeb. Ib qho peb-txoj kev StimulusType × Session × Qhov yuam kev hom kev sib cuam tshuam tau tshwm sim nyob rau hauv txhua pab pawg, txawm hais tias cov teebmeem yooj yim hauv txhua pab pawg tau qhia txog kev hloov pauv hauv cov lus teb rau Binge zaub mov stimuli nkaus xwb hauv BMR + RIT (saib Table 2, sab saum toj). Nyob rau hauv lub hauv paus, BMR + RITs qhia qhov ceeb toom tsis tseeb ntau dua li tsis nco qab rau cov duab binge zaub mov (χ2(1)=18.043, p<0.001), however, this was abolished post-training (χ2 (1)=1.222, p=0.269).

Yuav kom tsim nyog tau txais cov txiaj ntsig no, Kev Sib Tham × Kev Sib Koom Tes Kev Sib Koom Tes tau raug soj ntsuam nyob rau hauv txhua pab pawg thiab hom yuam kev (saib Table 2, hauv qab). Qhov no qhia tau hais tias muaj kev nce ntxiv hauv binge-food 'misses' los ntawm kev sib tham 1 txog ntu 3 hauv BMR + RIT, tab sis qhov kev poob qis tseem ceeb (piv txwv li cov lus teb ntau dua rau cov zaub mov binge) hauv BMR + Sham, qhia txog qhov muaj peev xwm ua rau muaj kev tsis ncaj ncees hauv qhov no. pab pawg. Nyob rau hauv NR + RIT, muaj qhov txo qis hauv cov lus ceeb toom tsis tseeb binge zaub mov 'tsis mus' kev sim thiab txo qis ntawm lub tswb cuav rau cov duab sau.

Kev ntsuas ntsuas ntsuas. Cov txheej txheem C. A 3 (Group) × 2 (Session: pre-manipulation, post-manipulation) × Stimulus Type (Binge, LPF, fller) factorial linear mix qauv nrog bootstrapped parameter kwv yees pom qhov cuam tshuam ntawm Stimulus Hom [F(2,450){ {6}}.59, p=0.028] thiab ib pab pawg × Session × Stimulus Type interaction[F(4,450)=3.011, p=0.018]. 3-txoj kev sib cuam tshuam tau tshawb xyuas los ntawm kev soj ntsuam ntawm Session × Pab pawg kev sib cuam tshuam rau txhua hom Kev Txhawb Nqa. Qhov no tau nthuav tawm Session * Pab pawg sib cuam tshuam rau cov duab binge nkaus xwb.

Hauv BMR+Sham, muaj qhov cuam tshuam loj heev ntawm cov lus teb tsis zoo rau cov zaub mov, cuam tshuam hauv kev txo qis hauv C forbinge cov duab los ntawm ntu 1 txog ntu 3 [F(1,90)=6.14, p{7}.015. Hauv BMR + RIT, muaj qhov txo qis hauv kev tsis ncaj ncees rau cov duab binge (nce hauv C ntawm 0) [F(1,90)=4.635, p=0.034]. Hauv NR+RIT tsis muaj kev hloov pauv tseem ceeb [F(1,90)=3.153,p=0.079]. Qhov no tuaj yeem ua pov thawj ntawm cov lus teb muaj txiaj ntsig hauv BMR + RIT, txawm hais tias nws yuav tsum tau muab sau tseg tias pawg no tau pom qhov kev tsis ncaj ncees loj tshaj plaws rau cov duab binge nyob rau ntu 1, qhia txog qhov muaj peev xwm ua tau raws li qhov cuam tshuam. Cov nyhuv no muaj nyob rau hauv daim duab 1.

D prime (d′). As with overall accuracy, d′ scores were highly skewed (z>4 feem ntau), qhia txog qab nthab-theem kev ua tau zoo txog kev mus / tsis mus teeb liab rhiab heev. Vim li no, d′ cov qhab nia tau txheeb xyuas siv gamma generalized linear sib xyaw qauv, suav nrog cov yam ntxwv ntawm Pawg, Hom Tshuaj, thiab Session factorially.Qhov no tau txais txiaj ntsig tseem ceeb ntawm Stimulus Hom nkaus xwb [F(2,522)=4.124, p=0.016], qhia qis d′ cov qhab nia (reflecting ntau dua lub tswb tsis tseeb) rau binge zaub mov dluab vs. non-food filler dluab [t(522)=2.783, p{{13} }.017], tab sis tsis muaj qhov sib txawv ntawm HPF thiab LPF stimuli [t(522){16}}.766, p=0.444].

Cov ntaub ntawv tshuaj xyuas lub sijhawm. Nyob rau hauv lub hauv paus, lub sij hawm nruab nrab ntawm cov tshuaj tiv thaiv ntawm (yog) 'Mus' sim qhia tau hais tias muaj kev cuam tshuam ntawm StimulusType [F(2,174)=8.447, p<0.001, η2 p=0.089], that was invariant across groups [Stimulus Type × Group interaction: F(4,174) = 1.948, p=0.105, η2 p=0.043]. Responses were faster to both types of food images (HPF and LPF) than non-food fller images [Helmert F(1,87)=14.82, p<0.001, η2 p=0.146], but not different between HPF and LPF images [Helmert F(1,87)=0.089, p=0.766, η2 p=0.001]. Tus there was an overall faster response to food images in the study sample, but not specifically to HPF 'binge' foods. A general speeding of responses between sessions 1 and 3 indicated practice effects [F(1,87)=32.643, p<0.001, η2 p=0.273], but there were no interactions nor group effects.

Oculomotor kev saib xyuas tsis zoo (visual sojntsuam). Nyob rau lub sij hawm ntsuam xyuas ntawm HPF / binge zaub mov vs LPF zaub mov cov duab pom tsis muaj pov thawj rau qhov sib txawv ntawm kev saib xyuas rau binge-food dluab saum toj no cov zaub mov ib se [maineffect of image type F(1,85)=2.79, p{ {5}}.099, η2p=0.032]. Qhov sib npaug, qhov no tsis txawv ntawm kev tswj hwm ua ntej [Session × Duab Hom F(1,85)=0.7, p=0.792, η2p=0.001] lossis hla Pawg [Session × Image Type × Group F(2,85)=0.43,p=0.65, η2p=0.01]. Lub sijhawm nyob rau ntawm qhov kev sim siab ntev (2000 ms) suav nrog kev siv tsis siv neeg thaum ntxov thiab tom qab ntawd nco ntsoov tswj kev pom kev pom.

Tseeb tiag, txo qis latencies rau thawj qhov kev kho ntawm cov duab binge zaub mov tau soj ntsuam (ib qho kev ntsuas ntawm qhov tsis siv neeg mloog) vs LPF cov duab [qhov tseem ceeb ntawm cov duab hom [F(1,85)=27.508,p<0.001, η2 p=0.245. Combined with the lack of difference in dwell time, this suggested that following initial (automatic) attentional capture, participants deployed effortful visual avoidance strategies to disengage attention from binge food images.
