Psychometric properties of the Thought-Action Fusion Scale in a Turkish sample

The aim of the present study was to reveal the cross-cultural utility of the Thought-Action Fusion Scale (TAFS; J. Anxiety Disord. 10 (1996) 379). Thought-action fusion (TAF) refers to the tendency to overvalue the significance and the consequences of thoughts. Two hundred and fifty one undergraduate Turkish students participated in the current study. The reliability and validity analyses of the Turkish version of the scale indicated that the TAFS had adequate psychometric properties in a Turkish sample. Consistent with the original TAF, the Turkish version of TAFS revealed two subscales as TAF-Likelihood and TAF-Morality. Reliability analysis showed that TAF Scale and its factors had adequate internal consistencies and split-half reliability coefficients. Confirming the expectations, TAFS scores were found to be significantly and positively correlated with obsessive-compulsive symptoms, responsibility, and guilt measures. Moreover, it was found that people with high obsessive-compulsive symptoms had higher TAFS scores than those with low symptoms.     

The characteristics of separation-individuation in Turkish High School students

The aim of the present study was examine the characteristics of separation-individuation in Turkish high school students and to investigate the contribution of sociodemographic variables on this second individuation process of adolescence. The sample consisted of 618 adolescents between the ages of 14 and 18 in three urban and two rural high schools (338 females and 280 males). Measures used included a demographic questionnaire and the Separation-Individuation Test of Adolescence (SITA), developed by Levin, Green, and Millon (1986). Results indicated that the 16-year-old group had significantly higher mean scores on the Engulfment Anxiety, Dependency Denial, and Rejection Expectancy subscales than the 15-year-old group. Males had significantly higher scores on the Practicing-Mirroring subscale than girls. Tenth graders had significantly higher mean scores on the Practicing-Mirroring, Nurturance Seeking, Peer Enmeshment, Teacher Enmeshment, and Healthy Separation subscales but the mean scores on the Dependency Denial and Engulfment Anxiety subscales decreased. The means scores on the Practicing-Mirroring, Dependency, Denial, Separation Anxiety, Teacher Enmeshment, and Rejection Expectancy subscales were significantly different among the socioeconomic status groups. Also, rural adolescents can be distinguished from urban counterparts by their increased tendency to perceive themselves as self-centered, to experience separation anxiety, to seek close interpersonal ties with caretakers, teachers, and peers, and by an integration of needs for dependence and independence. The general pattern of results investigating the separation-individuation development of Turkish adolescents suggested that compared with individualistic Western cultures, Turkish culture stressed the importance of connection as well as separation and psychic restructuring and interpersonal relatedness changes leading to an autonomous self within relational contexts.     

Measuring resistance to change at the within-session level

Resistance to change is often studied by measuring response rate in various components of a multiple schedule. Response rate in each component is normalized (that is, divided by its baseline level) and then log-transformed. Differential resistance to change is demonstrated if the normalized, log-transformed response rate in one component decreases more slowly than in another component. A problem with normalization, however, is that it can produce artifactual results if the relation between baseline level and disruption is not multiplicative. One way to address this issue is to fit specific models of disruption to untransformed response rates and evaluate whether or not a multiplicative model accounts for the data. Here we present such a test of resistance to change, using within-session response patterns in rats as a data base for fitting models of disruption. By analyzing response rate at a within-session level, we were able to confirm a central prediction of the resistance-to-change framework while discarding normalization artifacts as a plausible explanation of our results.     

Attitudes toward physical education classes of primary school students in Turkey

The purposes of this study were to report an investigation of attitudes toward physical education in a sample of primary school students and examine the predictive influence of students' sex, grades in physical education classes, and parents' education and socioeconomic status on students' attitudes. Participants, 963 (474 girls and 489 boys) primary school students from Grades 6 (12.7%), 7 (10.3%) and 8 (77%), completed the Wear Attitude Inventory. Analysis indicated students had positive scores on General Attitudes rather than on Social, Emotional, and Physical Attitudes. In addition, girls (M = 32.6, SD = 3.9) had more positive General Attitudes than boys (M = 32.0, SD = 4.6). Also, students' grades in physical education classes were statistically significantly related to their Attitudes toward physical education (Wilks lambda, F1,1110 = 2.88, p < .05). However, parents' education and socioeconomic status were not. One may infer that ways of encouraging more favorable attitudes might be planned.     

Precompetitive anxiety and affective state of climbers in indoor climbing competition

The purpose of this study was to measure the precompetitive anxiety and affective states of climbers, particularly with regard to sex and types of competition. 37 men (M=25.9, SD=3.8 yr.) and 10 women (M=25.9, SD=4.2 yr.), climbers who enrolled in Indoor Sport Climbing Competition, voluntarily participated in two different types of competition-speed and difficulty indoor climbing. The Competitive State Anxiety Inventory-2 and the Positive and Negative Affect Schedule were administered to all climbers just before the competition. The Sport Competition Anxiety Test was also administered to control competitive trait anxiety. Multivariate analysis of covariance yielded a significant interaction of sex and type of competition for affective state (Hotelling T2=0.21; F2,33=3.43, p<.05). Follow-up univariate analysis indicated that the mean Negative Affect score of women climbers before the difficulty competition was higher than mean Negative Affect scores of men before both speed and difficulty competitions and also the mean for women climbers before the speed competition (F1,34 = 6.15, p <.05). The results partially supported the hypothesis of differences in negative affect by sex and types of competition.     

Preliminary comparison of continuous versus noncontinuous programming and attitude toward and recall of advertisements

Need for continuity of a television program was assessed with attitude toward and recall of advertisements. The program continuity was manipulated experimentally by presenting one music video program as Top 10 (continuous) or as Regular (discontinuous) format. General attitude toward commercials and the belief in advertisement-product realism were investigated through the commercials with continuous and discontinuous formats of the same program. Data were gathered from undergraduates (23 men and 68 women) whose mean age was 20.2 yr. (SD=2.5). Analyses indicated continuity was not related to their attitude towards embedded commercials but was associated with their recall. Implications were discussed.     

Sensory versus cognitive components in harmonic priming

This study investigated the strength of sensory and cognitive components involved in musical priming. In Experiment 1, the harmonic function of the target chord and the number of pitch classes shared by the prime sequence and the target chord were manipulated. In Experiment 2, the temporal course of sensory and cognitive priming was investigated. For both musician and nonmusician listeners, cognitive priming systematically overruled sensory priming even at fast and very fast tempi (300 ms and 150 ms per chord). Cognitive priming continued to challenge sensory priming processes at extremely fast tempo (75 ms per chord) but only for participants who began the experimental session with slower tempi. This outcome suggests that the cognitive component is a fast-acting component that competes with sensory priming.     

Neural correlates of dual task interference in rapid visual streams: an fMRI study

In rapid streams of visual stimuli, identification of a first target interferes with identification of a second target presented within the next half second (the attentional blink or AB). It has been suggested that rapid perceptual decisions under masking interference involve interactions between frontal and posterior cortex. We investigated the neural correlates of the AB using functional magnetic resonance imaging (fMRI). Twelve subjects viewed rapid streams of black letters in which were embedded two white target letters (T1 and T2) separated by either 300 or 700 ms. As expected, fewer correct T2 identifications were observed in the short-delay condition. Corresponding fMRI statistical images showed increased activation in inferotemporal and posterior parietal cortex, but also in lateral frontal cortex and cerebellum in the short-delay condition suggesting that these brain regions are associated with perceptual decisions under masking interference.     

Alzheimer's disease disrupts arithmetic fact retrieval processes but not arithmetic strategy selection

Three groups of healthy younger adults, healthy older adults, and probable AD patients, performed an addition/number comparison task. They compared 128 couples of additions and numbers (e.g., 4 + 9 15) and had to identify the largest item for each problem by pressing one of two buttons located under each item. Manipulations of problem characteristics (i.e., problem difficulty and splits between correct sums and proposed numbers) enabled us to examine strategy selection and specific arithmetic fact retrieval processes. Results showed that arithmetic facts retrieval processes, which were spared with aging, were impaired in AD patients. However, AD patients were able to switch between strategies across trials according to problem characteristics as well as healthy older adults, and less systematically than healthy younger adults. We discuss implications of these findings for further understanding AD-related differences in arithmetic in particular, and problem solving in general.
