1 - Stimulus Repetition and Time Perception: Repetition Priming or Repetition Suppression?

Repetition priming usually is under- lined by improved behavioral performance, whereas in timing, the repetition suppression is accompanied by increasing error in time two estimations. This study investigated the possible simultaneous concurrence of these phenomena. Twelve adult subjects participated in a temporal oddball task in which the repetition of standard stimuli was under experimental manipulation, compard to the target stimulus. Both changes in performance and time representation were analyzed by a repeated measure within group design. Repeated presentations of temporal stimulus either in visual or auditory modalities improved participants behavioral performance (repetition priming). At the same time, data analysis for time representation showed that despite different directions in the modalities, the oddball stimulus was able to distort the time representation, both in time contraction and time expantion. The findings proposed that although the repetition priming can lead to faster and more accurate response, but more time distortions after repeated stimuli can be explained by the shift occured in errors distribution.

2 - Effects of Social Skills Group Intervention Based on DeRosier Program on Decreasing Externalizing Behavior Problems in Autistic Children with High Functioning

The present study has inves-tigated the effectiveness of a social skills group intervention based on DeRosier Program for decreasing externalizing behavior problems in children with high functioning autism. The study was done as a single-subject design using the A-B-A method. The statistical population consisted of children with high-func-tioning autism in Isfahan. Three students were selected using a purposeful sampling. The base-lines were drawn up using a subscale of Externalizing Behavior Problems (Social Skills Improvement System Rating Scales) (SSIS). There were 20 training sessions, each for 40 minutes which were held by the researcher. The evaluations were completed during the treatment and followed up by one the child specialist teacher one month later. Based on the results of the visual analysis of the data, this program has been effective in reducing behavioral problems (PND for participants respectively, 100%, 85.71%, and 100%). The results from PEM, NAP, TauU (at least 0.85%) indicate the effectiveness of this program. Therefore, the improvement of social skills in a group-based intervention has led to the growth of positive communicative experiences and reduced be-havioral problems for this group of children.

3 - Role of Schizophrenia Subscale in Explanation of Explicit Memory and Attention in a Non-Clinical Group

The method of the research was descriptive-correlational. To do so, 182 students from Bonab Payam Noor and some other universities were selected via cluster sampling method. Having chronic physical or mental or neurological diseases, or smoking or drug addiction were the exclusion criteria in this research. For gathering data, 78 items of MMPI-2 Sc scale, 90 words of Explicit Memory Test (EMT), and Toulouse-Pieron Attention Test (T-PAT) were used. The results of this research proved the predictive role of Sc character trait in the functioning explicit memory and selective attention (p<0.05), and indicated that with one unit change in Sc score explicit memory will change 0.29 unit and selective attention 0.17 unit in the opppsite direction.

Research has shown substantially in the last three decades that child abuse is a pathogenic factor for borderline personality disorder. The main purpose of this study was to predict the borderline personality disorder on the basis of childhood maltreatment and alexithymia, in nonclinical young adults. In this regard, 413 participants were selected using multistage sampling among all students studying in Tehran University. The Borderline Personality Scale (BPS), Child Abuse Self Report Scale (CASRS), and Toronto Alexi-thymia Scale (TAS-20) were used to measure variables. The raw data collected, was analyzed by structural equation modeling. The findings were similar to results of previous studies. The results indicate that theoretical model has a good fitness and childhood traumatic experiences (specially emotional abuse) and alexithymia are good predictors for borderline personality disorder. In addition, results revealed that alexithymia mediated rela-tionship between maltreatment and BPD symptoms Manuscript profile -

The population comprised of the 200 senior high school female students from district 2 of Tehran who were enrolled in 2014-2015 academic year selected by multistage cluster sampling. For data collection Attachment Style Questionnaire (ASQ) by Collins and Reid, Toronto Alexithymia Scale (TAS), and Inventory of Interpersonal Problems (IPT) were used. Analisis of results based on Pearson correlation and stepwise linear regression showed that significant relationships exist among attachment styles, alexithymia, and inter-personal problems (P<0/01). Furthermore, the attachment components were capable of predicting alexithymia (about 22%) and inter-personal problems (about 27%). Manuscript profile -

The purpose of the present study was to investigate and compare the impact of three types of peer tutoring on students’ mathematic achievement and motivation in multi-grade classes. The research sample consisted of two multi-grade classes selected from villages in Yasouj City during academic year 2015-2016. Sample members were selected via purposeful sampling method and were randomly assigned to control and test groups. The research instru-ments included teacher-made tests and semi-structured interviews with parents and tea-chers. The control group subjects were instruc-ted by traditional method of teaching. Fin- dings showed that not only peer-tutoring method had a considerable effect on students’ mathematical achievement, but also led to improved motivation for mathematics learning, social relationships, cooperation and team work inclinations among them.
