The effect of true and false feedback on blushing in women

The effect of true and false feedback of facial blood flow on blushing and embarrassment was investigated in high (n=24) and low (n=24) scorers on the Blushing Propensity Scale. Feedback was given while the participants sang and read aloud. Blushing while singing habituated rapidly in both groups and was not affected by true feedback. Blushing still developed in high scorers when given false-negative feedback of blushing when they first sang, whereas low scorers did not blush. False-positive feedback of blushing while reading aloud increased embarrassment, but facial blood flow decreased. High scorers gave higher ratings for embarrassment and blushing than low scorers during most of the tasks. The findings suggest that people who think that they are prone to blushing feel more self-conscious but generally do not blush more intensely or frequently than people with low blushing propensity scores during clearly embarrassing or innocuous social encounters. However, expecting to blush might actually increase the likelihood of embarrassment and blushing in potentially embarrassing situations.     

Effects of perspective and belief on analytic reasoning in a scientific reasoning task

The purpose of these studies was to test the hypothesis that changing perspectives from one's own to another's promotes the engagement of analytic processing and, in turn, reduces the impact of beliefs. In two experiments participants evaluated research vignettes containing belief-consistent and belief-inconsistent conclusions, and indicated whether the data supported a correlation between two variables. Consistent with our hypothesis, the tendency to endorse correlations consistent with prior belief was reduced when participants evaluated the data from the researcher's perspective relative to their own. We also administered the Actively Open Minded Thinking (AOT) scale (Stanovich & West, 2007, 2008), which did not predict belief effects on our task. We did however observe that the AOT was reliably associated with different response strategies: high AOT scorers were more inclined to choose ambiguous response options, such as “no conclusion is warranted”, whereas low scorers evinced a preference for more determinate options (e.g., there is no relationship between the two variables). We interpret our findings in the context of dual process theories of reasoning and from a Bayesian perspective.     

Nonregulation of food intake in restrained,emotional, and external eaters

In the present study, regulation of ice cream intake after a preload was examined in 20 high and 20 low scorers (median split) on subscales of the Restraint Scale (RS) (Herman, Polivy, Pliner, Threshold, & Munic, 1978) and the Dutch Eating Behavior Questionnaire (DEBQ) (van Strien, 1986). For each subscale it was hypothesized that low scorers would regulate their ice cream intake. High scorers on disinhibitive scales (i.e., the RS and the DEBQ-emotional and -external subscales) were expected to counterregulate after a preload. In contrast, high scorers on the inhibitive DEBQ-restraint scale were expected to regulate their ice cream intake. A robust effect was found: high scorers never regulated ice cream intake after a preload on either the disinhibitive or the inhibitive scales, while low scorers always did. For the RS a significant interaction effect was found [F(1,39)=4.97, p=.03]. None of the other subscales showed interaction effects. The t tests showed that low scorers on all subscales ate significantly less after a preload than without one, while high scorers on all subscales did not differ in intake after a preload or without one. This nonregulation appears to be characteristic of people preoccupied with caloric intake, regardless of the content of the preoccupation.     

A cognitive style approach to creative thought.

Creative thinking was explored from several approaches to further understanding of the interrelationship of perception, personality, and cognition. College students (N = 45) were administered the Group Embedded Figures Test (GEFT), the Remote Associates Test (RAT), a questionnaire concerning RAT strategy, and two self-report scales. Field independent subjects were found to be significantly (p less than .001) more creative than field dependents. Correlations between the RAT and GEFT and the self-report measures of conformity and creativity, while largely nonsignificant, were in the predicted directions. Results demonstrated that advanced strategy levels and insightful responses were significantly related to high performance on the RAT. Theoretical links between cognitive style and Piagetian concepts were discussed in regard to creative thought. Overall, these findings support the contention that the creative processes should be studied, not as isolated structures, but with relational and multifaceted emphasis.     

Social fear and expressive reactions to social stimuli

This study explored whether subjects high as compared to low in social fear react with a more negative emotional response, measured as facial electromyographic (EMG) activity, when exposed to social stimuli (pictures of angry and happy facial expressions). It was found that subjects who rated themselves as relatively high in public speaking fear gave larger negative facial EMG responses (Corrugator supercilii muscle activity) to angry faces than did the low fear subjects. Low fear subjects, on the other hand, gave larger positive facial EMG responses (Zygomatic major muscle activity) to happy faces than did the high fear subjects. It was further found that happy stimuli were rated as more hostile and less friendly and happy by the high fear group. Consistent with earlier findings, it was concluded that the facial EMG technique is sensitive to detecting different reactions among subjects relatively high and low in social fear.     

Personality and biological markers of creativity

The aim of the present study was to test (i) Eysenck's theory that psychoticism (P) should be related to creativity, (ii) whether testosterone (T), due to its association with P claimed in the literature, can be identified as a biological marker of creativity, and (iii) whether the SEEK dimension of the Affective Neuroscience Personality Scales (ANPS) was also related to creativity and to testosterone due to its relationship to Sensation Seeking. In a sample of N = 48 male and female subjects, test scores on figural, verbal, and numeric creativity were compared between high and low P‐scorers as well as between high and low SEEK‐scorers. Effects were controlled for fluid intelligence as measured by Cattell's CFT‐3 and crystallized intelligence as assessed by the Structure‐of‐Intelligence‐Test (Intelligenz‐Struktur‐Test, I‐S‐T 2000 R). Neither a main effect of P or T nor an interaction effect P×T on creativity could be obtained. Instead, SEEK was related to all components of creativity and explained more than 15% of the variance of total creativity. Moreover, significant differences in SEEK could be explained by differences in T, independently of gender. Furthermore, 39% of the variance of SEEK could be explained by the two uncorrelated indicators testosterone and creativity. Copyright © 2004 John Wiley & Sons, Ltd.     

Personality and sex differences in emotional responsiveness to positive and negative cognitive stimuli

To investigate the influence of psychoticism (P) and neuroticism (N) on emotional responding, a re-analysis was carried out on subjective and physiological data collected while Ss (n = 50) repeatedly imagined anxious (intrusive) or depressive, and pleasant thoughts or images. High N was associated with a greater negative mood state subsequent to imagining the distressing cognitive stimuli, though there was no relation with physiological reactivity. However, high P scorers did evidence less overall cardiac reactivity and, to a lesser extent, fewer skin resistance responses than low P Ss. The results are discussed in light of the moderating influence that stimulus and response characteristics as well as gender differences can have on the interaction between personality traits and emotional responding.     

字谜与远距离联想解决中认知成分的比较

采用自发顿悟范式,通过事件相关电位(ERPs)探讨字谜和远距离联想（RAT）两类顿悟问题解决中的认知差异。结果发现,两类任务的正确反应时均在4000ms左右;解决两类任务的初期都在170ms时出现了正成分,且两类任务在此成分上没有显著差异;在600~700ms内,字谜比RAT诱发了一个更正的ERP成分,主要激活了中后部的脑区;在按键前的800~400ms内,字谜较RAT在右前额诱发了更正的脑电成分。结果表明,字谜顿悟和RAT顿悟存在相似的加工过程,但在重构阶段和啊哈体验上存在差异;两类任务在解决问题时重构过程的不同可能是造成情绪体验差异的原因     

Categorical perception of anger is disrupted in alexithymia: Evidence from a visual ERP study

High and low alexithymia scorers were confronted with a modified visual oddball task that allowed the study of categorical perception of emotional expressions on faces. Participants had to quickly detect a deviant (rare) morphed face that shared or did not share the same emotional expression as the frequent one. Expected categorical perception effects, which were also neurophysiologically indexed, showed that rare stimuli were detected faster if they depicted a different emotional expression compared to rare stimuli depicting the same emotional expression than the frequent one. Even if no differences were observed at a behavioural level, high alexithymia scorers evidenced overall delayed neurophysiological responses in components related to the attentional processing of rare emotional faces. Moreover, the categorical perception effects for event-related components associated with the attentional processing were smaller in high alexithymia scorers and were even absent for anger. These results show that high alexithymia scorers present discrimination delays that are already observed at the attentional level.     

Highs Are to Lows as Experts Are to Novices: Individual Differences in the Representation and Solution of Standardized Figural Analogies

Two experiments compared the strategies used by high and lower scorers on standardized figural analogy tests to represent and solve problems. In Experiment 1, subjects freely sorted completed analogy (A:a::B:b) problems into categories. High scorers categorized problems largely on the basis of well-constrained spatial transformations between problem terms; Low scorers sorted according to perceptual (i.e., shape) similarities among the figures constituting the problems. Experiment 2 compared the two groups' solution strategies in terms of specific patterns of eye movements used in viewing problem and answer terms. High scorers appeared to view problem terms in a more efficient fashion than did lower scorers. The lower scorers focused on noncritical figural relations (mapping figure A onto figure B), and they devoted more resources to processing the answer alternatives than did the high scorers. The pattern of results supports the view that high scorers tend to work in a more forward, or constructive, fashion, whereas lower scorers more often work backwards, using a response-elimination approach. Taken together, these findings converge to suggest specific aptitude-related differences in the representation and solution of standardized figural analogy problems. These differences bear some similarities to expert-novice differences in a number of other problem-solving domains.     

Normative data for Chinese compound remote associate problems

The Remote Associates Test (RAT) is a well-known measure of creativity, with each item on the RAT is composed of three unrelated stimulus words. The participant’s task is to find an answer in the form of a word that could combine with each of the stimulus words, thus forming three new actual nouns. Researchers have modified the RAT to develop compound remote associate problems that emphasize combining vocabulary to form compound words. In the field of creativity research for Mandarin speakers, the Chinese RAT has been widely applied for over 10 years. The original RAT, compound remote associate problems, and Chinese RAT have various common advantages, such as being convenient to use and having objective scoring; additionally, the development of items for certain tests is easy and satisfies the requirements of psychological assessments in terms of the quantity of items. Currently, many language editions of the RAT and compound remote associate problems already exist. In particular, the English and Italian versions of these tests already have derived normative data. Because approximately 20% of the world’s population are native Mandarin speakers, and because increasing numbers of people are choosing Mandarin as a second language, the need to increase Mandarin-language resources is growing; however, normative data for the Chinese RAT still do not exist. To address this issue, in the present study we developed Chinese compound remote associate problems and analyzed the passing rates by items, problem solving times, and various normative data, using the responses of 253 subjects in three experiments.     

Assessment of Personality Organization in Couple Relationships: Factorial Structure of the Inventory of Personality Organization and Incremental Validity Over Neuroticism

Summary: Creative thinking was explored from several approaches to further understanding of the interrelationship of perception, personality, and cognition. College students (N = 45) were administered the Group Embedded Figures Test (GEFT), the Remote Associates Test (RAT), a questionnaire concerning RAT strategy, and two self-report scales. Field independent subjects were found to be significantly (p < .001) more creative than field dependents. Correlations between the RAT and GEFT and the self-report measures of conformity and creativity, while largely nonsignificant, were in the predicted directions. Results demonstrated that advanced strategy levels and insightful responses were significantly related to high performance on the RAT. Theoretical links between cognitive style and Piagetian concepts were discussed in regard to creative thought. Overall, these findings support the contention that the creative processes should be studied, not as isolated structures, but with relational and multifaceted emphasis.     

Effect of schizotypy on responding maintained by free-operant schedules of reinforcement

Deviations from otherwise reliable patterns of responding in human performance on schedules of reinforcement could be associated with personality characteristics, such as psychometrically-measured schizotypy. The present study examined differences between high and low scorers on four schizotypy subscales (unusual experiences, cognitive disorganisation, introvertive anhedonia and impulsive non-conformity) on a random-ratio (RR) and random-interval (RI) schedule of reinforcement. Results showed a higher rate of responding on the RR than RI schedule, consistent with the differences in performance normally observed between these schedules. However, these differences were dependant on whether or not participants scored high or low on the schizotypy subscales, as well as the specific schedule parameters between the schedules. Specifically, high scorers on the unusual experiences (UE) subscale of the O-LIFE(B) were the only group in Experiment 1 not to show a difference in schedule performance, suggesting high scores on this subscale are linked to altered RR and RI performance. Experiment 2 explored this finding further using different schedule parameters, and confirmed that high scorers in UE did not differ in response rates between the two schedules.     

Psychoticism and sexual arousal to rape depictions

This study tested the hypothesis that high scorers on the Eysencks' P scale would become more sexually aroused by erotic material of a violent nature than low scorers. One hundred and forty-five college Ss were exposed to erotic auditory messages varying in degree of violence and pain experienced by the victim. Personality was assessed by a median split on the Eysencks' P scale. Sexual arousal was assessed by mercury strain gauge and self-report. Results, as predicted, showed a significant interaction between psychoticism and level of violence (rape vs nonrape): high P scorers showing greater sexual arousal (by both self-report and physiological assessment) to rape as compared to nonrape depictions whereas the opposite pattern occurred for low P scorers.     

Personality and the perception of TV violence

An experiment was carried out to investigate relationships between individuals' personality characteristics and their perceptions of violent TV portrayals. A panel of 40 viewers rated brief violent episodes from five categories of programming, contemporary British crime-detective series, American police series, westerns, science-fiction series and cartoons on eight scales. These responses were then related to viewers' scores on the N, E and P dimensions of the EPQ. Results showed that violent scores from contemporary settings were rated as more serious than scores from non-contemporary and fantastic settings. In addition, viewers exhibited individual differences in ratings of TV violence which were related to certain of their EPQ scores. In particular, high N scorers tended to perceive violence generally, but especially that from contemporary British drama, as more serious than did low N scorers. This study indicates the need to include personality measures in the analysis of audience reactions to TV violence.     

The psychophysiology of James Bond: phasic emotional responses to violent video game events

The authors examined emotional valence- and arousal-related phasic psychophysiological responses to different violent events in the first-person shooter video game "James Bond 007: NightFire" among 36 young adults. Event-related changes in zygomaticus major, corrugator supercilii, and orbicularis oculi electromyographic (EMG) activity and skin conductance level (SCL) were recorded, and the participants rated their emotions and the trait psychoticism based on the Psychoticism dimension of the Eysenck Personality Questionnaire--Revised, Short Form. Wounding and killing the opponent elicited an increase in SCL and a decrease in zygomatic and orbicularis oculi EMG activity. The decrease in zygomatic and orbicularis oculi activity was less pronounced among high Psychoticism scorers compared with low Psychoticism scorers. The wounding and death of the player's own character (James Bond) elicited an increase in SCL and zygomatic and orbicularis oculi EMG activity and a decrease in corrugator activity. Instead of joy resulting from victory and success, wounding and killing the opponent may elicit high-arousal negative affect (anxiety), with high Psychoticism scorers experiencing less anxiety than low Psychoticism scorers. Although counterintuitive, the wounding and death of the player's own character may increase some aspect of positive emotion.     

Adherence to substance abuse treatment: clinical utility of two MMPI-2 scales.

In this study, we examined the ability of the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Addiction Acknowledgment scale (AAS; Weed, Butcher, McKenna, & Ben-Porath, 1992) and Negative Treatment Indicators scale (TRT; Butcher, Graham, Williams, & Ben-Porath, 1990) to predict adherence to and outcomes from substance abuse treatment. There was no evidence that the AAS was related to treatment adherence or outcome in our sample. However, results did reveal a significant positive relation between scores on the TRT scale and readmission to the hospital. Further analyses identified an optimal score for use in similar clinical populations and settings, and characteristics of high and low scorers. Compared to low scorers, high TRT scorers were more likely to not return for treatment after an initial screening interview. If they did return for treatment, high TRT scorers were more likely to experience fewer treatment days and to be rated as having lower motivation, poorer participation, and poorer comprehension of program materials. These findings provide promising initial evidence of the utility of the TRT scale for identifying patients who may be at a high risk for unsuccessful substance abuse treatment.     

SACRAL: toward the meaning and measurement of friendliness

Friendliness was regarded as a construct or dispositional tendency consisting of four components: Self-concept (S), the person's beliefs about self related to peer relationships; Accessibility (AC), giving behaviors involving attention and respect; Rewardingness (R), the giving of more tangible rewards, such as money and compliments; and Alienation (AL), personal beliefs about acceptance and the world as a friendly place. A 40-item questionnaire was developed to assess these components of friendliness. Studies of the questionnaire with college students and children supported its internal consistency, test-retest reliability, concurrent validity, construct validity, and discriminant validity. Although virtually all respondents reported themselves as friendly, high SACRAL scorers, when compared with low scorers, less frequently experience loneliness and in a variety of contexts claim to be more apt to engage in friendly behaviors. The impression that emerges of relatively low scorers on SACRAL is of people whose professed actions are somewhat inconsistent with their personal beliefs.
