Sex differences in student—teacher interactions in the college classroom

An observational analysis of student—teacher interactions in 60 college classes revealed sex differences in student behaviors. Male students were the majority sex more often than females in classes taught by male lecturers; there was no sex difference for classes taught by female lecturers. Male students engaged in proportionately more student—teacher interactions than female students in male-taught classes; there was no sex difference in female-taught classes. Neither male nor female professors appeared to respond differentially to male and female students. Possible causes and implications of these findings are discussed.Portions of this paper were presented at the biennial meeting of the Society for Research in Child Development, Denver, April 1975.     

Do differences in general trust explain cultural differences in dispositionism?1

Abstract: It has been suggested that Westerners are more inclined than Easterners to endorse dispositionism. To help explain what produces this cultural difference, I examined the responses of Japanese and American students to determine whether levels of general trust, which is the expectation of benign or cooperative behavior based on the goodwill of another person (Yamagishi & Yamagishi, 1994), would matter. As predicted, in accounting for either a prosocial or deviant behavior, high trusters were more likely than low trusters to show dispositionism on all three measures (dispositional attribution, trait inference, and behavioral consistency), whereas cultural differences in dispositionism almost vanished. This tendency was found regardless of the desirability of behaviors.     

Individual differences for sex differences in achievement attributions?

Past research has found a self-defensive bias in males and a self-derogatory bias in female achievement attributions. Dispositional explanations for these differences were examined in the present study. Subjects completed measures of Need for Achievement, Self-Esteem, Fear of Success, Attitudes Toward Women, and Androgyny. They later competed in same- or mixed-sex pairs on an anagram task which was prearranged in difficulty so that one subject clearly defeated his/her partner. Consistent with past research, males were more likely to attribute their outcomes to ability, and less likely to attribute their outcomes to effort and luck, than were females. Achievement motivation was the most consistently successful predictor of these sex differences.     

Response mode differences in perspective taking: Differences in representation or differences in retrieval?

Three experiments explored whether response mode differences in perspective taking result from different spatial representations or different retrieval processes. Participants learned object locations and then, while blindfolded, pointed to or verbally described object locations from perspectives aligned or misaligned with their facing direction and aligned or misaligned with the learning perspective. Pointing was facilitated from the perspective aligned with the body during testing. Similar facilitation occurred when verbally labeling, but only when conducted in the context of pointing (e.g., after pointing). Without this pointing context, or after third-person strategy instructions, the effect of body alignment was eliminated for verbal responses. Pointing was less responsive to context and strategy. Across all conditions, performance was facilitated for the learning perspective. Taken together, these experiments indicate that response mode differences are due to differences in the retrieval process, which varies with strategy, rather than differences in the organization of the underlying spatial memory.     

Do sex differences in emotionality mediate sex differences in traits of psychosis-proneness?

The aim of the study was to determine if sex differences in emotionality might account for sex differences in distinct traits of proneness to psychosis (or "schizotypy"). Females report higher levels of "positive" schizotypy (e.g., magical thinking) than males, along with a tendency toward greater schizotypal disorganisation, whereas males report higher levels of "negative" schizotypal traits, such as social anxiety (Jackson & Claridge, 1991; Raine, 1992). Given the affect-oriented nature of "negative" schizotypal traits, we tested the hypothesis that higher levels of "negative" schizotypy among males would be accounted for by more general sex differences in emotionality; that is, by less frequent and less intense emotional experiences. A total of 81 student participants were administered the Cognitive-Perceptual Deficits, the Disorganisation, and the Interpersonal Deficits components of Raine's (1991) Schizotypal Personality Questionnaire (SPQ), indexing respectively, "positive" schizotypy, schizotypal disorganisation, and "negative" schizotypy. Frequency of emotional experience was assessed using the Emotionality subscale (Buss & Plomin, 1984) and intensity, the Affect Intensity Measure (Larsen & Diener, 1987). As predicted, males scored significantly higher than females on the SPQ Interpersonal Deficits component but no sex differences emerged for the other two components. Males reported significantly less intense, although not less frequent, experiences than females. A reduced intensity of positive emotions in particular was found to mediate the sex difference in "negative" schizotypy. Our results suggest that a less intense experience of positive affect might contribute to males' propensity to develop negative symptoms should a schizophrenic breakdown occur.     

Are you talking to me?! Separating the people from the problem when expressing emotions in negotiation

Emotions such as anger and happiness have pervasive interpersonal effects in negotiations. We propose that the nature of the effects depends on the target of the emotion, that is, whether the emotion is directed toward a person or a specific behavior. In a computer-mediated negotiation (N = 87), participants received either angry or happy messages from a simulated opponent, which were either behavior-oriented or person-directed. Behavior-oriented anger elicited larger concessions than behavior-oriented happiness, whereas person-directed anger elicited smaller concessions than person-directed happiness. This reversal could be attributed to the strategic value of the emotional expression, which was higher in the behavior-oriented condition than in the person-directed condition. These findings show that the interpersonal effects of anger and happiness depend critically on the target of the emotion.

Is more choice always worse? Age differences in the overchoice effect

Current research on the overchoice effect has been mainly conducted from an adult point of view and with adult subjects. This study investigates whether children, adolescents, and seniors suffer the same negative consequences as adults when facing an overabundance of choice. Findings showed that the overchoice effect did not equally extend to all age groups. While adolescents were affected by the phenomenon in a very similar way as adults, children and seniors suffered fewer negative consequences of an overabundance of choice. Theoretical and practical implications are discussed.     

Can practice overcome age-related differences in the psychological refractory period effect?

Can dual-task practice remove age-related differences in the psychological refractory period (PRP) effect? To answer this question, younger and older individuals practiced 7 blocks of a PRP design, in which Task 1 (T1) required a vocal response to an auditory stimulus and Task 2 (T2) required a manual response to a visual stimulus (Experiment 1). The results showed that practice did not reduce, but rather increased, age-related differences in PRP interference. Using the trained individuals, the introduction of a less complex new T1 (Experiment 2) or a less complex new T2 (Experiment 3) with the task previously practiced reduced the PRP interference but only in older adults. The authors propose that older adults suffer from a large task-switch cost that is more sensitive to task complexity than to the amount of practice.     

Variability of color choice in the Lüscher Color Test--sex differences

In this preliminary investigation of variability of responses on the Lüscher Color Test, subjects were 567 volunteers administered the test twice with a 10-min. interval between them. Two hypotheses were tested: (a) that variability of responses attests to the personality of the respondent (tested by the relations of variability and MMPI scale scores), and (b) variability of responses is based on learning the test's content. As such, men's scores should be more variable than women's. Analysis showed that variability was not correlated with scores for personality on the MMPI scales. Men's scores are more variable than women's, but only until age 45.     

What do people value when they negotiate? Mapping the domain of subjective value in negotiation

Four studies support the development and validation of a framework for understanding the range of social psychological outcomes valued subjectively as consequences of negotiations. Study 1 inductively elicited and coded elements of subjective value among students, community members, and practitioners, revealing 20 categories that theorists in Study 2 sorted into 4 underlying subconstructs: Feelings About the Instrumental Outcome, Feelings About the Self, Feelings About the Negotiation Process, and Feelings About the Relationship. Study 3 proposed a new Subjective Value Inventory (SVI) and confirmed its 4-factor structure. Study 4 presents convergent, discriminant, and predictive validity data for the SVI. Indeed, subjective value was a better predictor than economic outcomes of future negotiation decisions. Results suggest the SVI is a promising tool to systematize and encourage research on subjective outcomes of negotiation.     

SES differences in young children’s metacognition in the context of mathematical problem solving

This investigation examines socioeconomic (SES) differences in young children’s development of key aspects of metacognition and related language. The participants were 102 children ranging in age from 4 years 0 months to 5 years 11 months in five daycare centers located in New York City. Metacognitive abilities and language were observed as children engaged in an individually administered clinical interview concerning mathematical problem solving. The results indicate that the ability to describe thinking and explain ideas is stronger in the upper-SES group than the middle- or lower-SES groups. The findings also indicate that all the SES groups, and children of both ages, show little awareness of mistakes and adaptability without adult assistance. The capacity to express thinking was found to increase with age during early childhood. The results suggest that young children begin to employ rudimentary forms of metacognition before the onset of formal schooling. Implications for education are discussed.     

Parenting and children's aggression: are there differences in the influence of the father and the mother?

Child rearing provides messages and rules that mediate the children's personality. These messages have a positive or negative influence on their behaviour. The objective of this empirical study was to analyse the relationship between physical and verbal aggression of sons and daughters and parenting style practiced by the father and the mother. The sample consisted of 2,788 students, aged 10 to 15 years, studying either the third cycle of Primary Education (44%) or the first cycle of Secondary Education (56%). Of them, 1,412 were boys (50.6%) and 1,375 were girls (49.3%). The results show that children's aggressiveness is more related to factors associated with the mother's parenting. In the case of daughters, the influence of parenting factors are caused by both parents (father and mother).     

Placing age differences in the context of the Orissa supercyclone: Who experiences psychological distress?

The present study examines the influence of age on anxiety, depression, and post-traumatic stress of the supercyclone-affected people in Orissa. The data were collected in structured interview sessions 3 months after the disaster struck. Of the 130 interviewees, 65 persons were severely exposed and the rest were mildly exposed to the supercyclone. When the effects of exposure, caste, and gender were controlled, linear effects of age on psychological distress were found to be significant, whereas quadratic effects of age on psychological distress were non-significant. With increasing age, survivors experienced more anxiety, depression and post-traumatic stress. The elderly people were the most vulnerable.     

Two meanings of "if"? Individual differences in the interpretation of conditionals

This work investigates the nature of two distinct response patterns in a probabilistic truth table evaluation task, in which people estimate the probability of a conditional on the basis of frequencies of the truth table cases. The conditional-probability pattern reflects an interpretation of conditionals as expressing a conditional probability. The conjunctive pattern suggests that some people treat conditionals as conjunctions, in line with a prediction of the mental-model theory. Experiments 1 and 2 rule out two alternative explanations of the conjunctive pattern. It does not arise from people believing that at least one case matching the conjunction of antecedent and consequent must exist for a conditional to be true, and it does not arise from people adding the converse to the given conditional. Experiment 3 establishes that people's response patterns in the probabilistic truth table task are very consistent across different conditionals, and that the two response patterns generalize to conditionals with negated antecedents and consequents. Individual differences in rating the probability of a conditional were loosely correlated with corresponding response patterns in a classical truth table evaluation task, but there was little association with people's evaluation of deductive inferences from conditionals as premises. A theoretical framework is proposed that integrates elements from the conditional-probability view with the theory of mental models.     

Who takes the most revenge? Individual differences in negative reciprocity norm endorsement

The authors report that beliefs favoring the reciprocation of unfavorable treatment form a unitary factor that is distinct from beliefs favoring the reciprocation of favorable treatment. Individual differences in endorsement of this negative reciprocity norm were related to (a) beliefs that people are generally malevolent; (b) inclination toward anger in everyday life; (c) anger, disagreement, and ridicule directed toward a new acquaintance who treated participants unfavorably; and (d) reduced anxiety, positive emotional engagement, and encouragement of a new acquaintance who treated participants favorably. These findings suggest that individual differences in endorsement of the negative norm of reciprocity influence the extent of vengeance.     

Individual differences in the vibrotactile perception of a “simple” pattern set

Discriminative capacities for vibrotactile spatiotemporal patterns were examined in 62 college students with three tasks: identification, masking, and discrimination of the letters “X” and “O” presented tactually on the Optacon, a reading machine for blind persons. Individual differences in performance and interrelations among scores within and across paradigms were explored. In identification, most persons quickly achieved consistently better than 90% performance, but others failed to identify the patterns above 80%, even after prolonged training. The same performance variance was found when the task was repeated by 23 Naval student pilots. Masking and discrimination measured susceptibility to interference when patterns followed one another closely in time. The resulting functions were typical, with poorest performance at short stimulus onset asynchronies. Again, a wide range of performance was seen. Individual performance, however, appeared to be consistent across tasks, suggesting that abilities in a variety of pattern-perception tasks might be predictable.
