Grouping, chunking, memory, and learning

An example of grouping is dividing a long series of digits into two or more smaller units by, for example, pausing for a short time between items within groups but for a longer time between groups. Grouping, virtually neglected in animal learning, was examined in each of five rat investigations reported here in which a series of two or more runway trials was either grouped together with or apart from a terminal large reward trial. It was found that running speed on early small reward trials in the series was greater when prior trials were grouped together with rather than apart from the terminal large reward trial and this when the intertrial interval was short, 20 sec, or long, 20 to 40 min. Three possible explanations of the present findings were examined: a reward schedule view, a rule-learning view, and an anticipation view based on memory. The most feasible of these explanations, it was suggested, was the anticipation view. According to this view, when prior trials are grouped together with a terminal large reward, there is a tendency for the rat to anticipate the terminal large reward well before its scheduled occurrence, elevating running speed on earlier small reward trials. Such anticipation occurs, it was suggested, because when trials are grouped together the memory of each reward event in the series is retrieved on each subsequent trial, including the remote terminal large reward trial, where it becomes a signal for large reward. Thus the present results implicate not merely adjacent associations—associations between adjacent events—but also the highly controversial remote associations—associations between two events separated not only in time but by one or more intervening events as well.     

Contrast, induction, facilitation, suppression, and conservation

Ten rats received all of their water in daily 1-hr sessions. Following a baseline phase in which lever and water spout were freely available throughout each session, subjects were trained to press the lever for water on mixed schedules composed of two alternating components. Each component gave access to water for a fixed cumulation of drinking time every time the rat cumulated a fixed amount of lever-pressing time. Changes in one component produced contrast and induction effects, both positive and negative, with respect to both lever pressing and drinking in the unchanged component. All schedules facilitated lever pressing relative to baseline. All schedules suppressed drinking relative to baseline, even though contingency sessions allowed ample time to perform the baseline amount of drinking. The entire pattern of results was predicted in quantitative detail by assuming that the total amount of a dimension apportioned to lever pressing and drinking is conserved between baseline and contingency sessions. Conservation theory was shown to predict several effects produced by simple fixed-ratio schedules, and was compared favorably with probability-differential (Premack, 1971) and response-deprivation (Timberlake and Allison, 1974) theory.     

Narrow-band 1, 2, 3, 4, 8, 16, 24, 32, 48, 64, and 96 cycles/360 degrees angular frequency filters

We measured human frequency response functions for eleven angular frequency filters using a forced-choice procedure in a supra-threshold summation paradigm. Each of the eleven functions of 17 experimental conditions was measured 4-9 times among 12 observers. Results show that, for the arbitrarily selected filter phases, maximum summation effect occurred at test frequency for all filters. These results lead to the conclusion that there are narrow-band angular frequency filters operating in human visual system mostly through summation surrounded by inhibition at the specific test frequency ranges. Our previous suggestion (Simas and Santos, 2002), arguing that summation for the higher angular frequency filters should occur if background angular frequency contrast were set to a maximum of 5 times the test frequency threshold, was supported.     

Wishes, Gender, Personality, and Well-Being

ABSTRACT Study participants (175 men, 230 women) made three wishes and completed measures of the five-factor model of personality, optimism, life satisfaction, and depression. Common wishes were for achievement, affiliation, intimacy, and power as well as for happiness and money. T tests showed women were more likely to wish for improved appearance, happiness, and health; men were more likely to make power wishes and wishes for sex. Among participants who were highly involved in the wishing process, Extra-version was related to making more interpersonal wishes and wishes for positive affect. Neuroticism was related to wishes for emotional stability. Agreeableness and Openness to Experience related to wishes reflective of these traits. Conscientiousness was related to low impulsivity. Depression was related to making highly idiosyncratic, specific wishes, suggesting the use of wishful thinking as a coping mechanism. In addition, happy participants were more likely to rate their wishes as likely to come true. Results indicate that the relatively commonplace process of wishing relates to traits, gender, and well-being.     

Note taking, review, memory, and comprehension

In previous work assessing memory at various levels of representation, namely the surface form, textbase, and situation model levels, participants read texts but were otherwise not actively engaged with the texts. The current study tested the influence of active engagement with the material via note taking, along with the opportunity to review such notes, and the modality of presentation (text vs. spoken). The influence of these manipulations was assessed both immediately and 1 week later. In Experiment 1 participants read a text, whereas in Experiment 2 participants watched a video recording of the material being read as a lecture. For each experiment the opportunity to take notes was manipulated within participants, and the opportunity to review these notes before the test was manipulated between participants. Note taking improved performance at the situation model level in both experiments, although there was also some suggestion of benefit for the surface form. Thus, active engagement with material, such as note taking, appears to have the greatest benefit at the deeper levels of understanding.     

Forgiveness in adolescents, young, middle-aged, and older adults

The evolution of the propensity to forgive an offense was studied in a sample of 236 people from various age groups. The effect of a number of circumstances connected with the offense was considered: intent to harm, severity of consequences, cancellation of consequences, social proximity to the offender, apologies from the offender, and the attitude of others. The method was an application of information integration theory. A global increase in the propensity to forgive from adolescence to old age was observed. Several interactions between age and circumstances were found: (a) The effect of the cancellation factor was higher in young adolescents and in the very old than in the middle-aged, (b) the attitude of others and the restoration of harmony factors were important only in adolescents. Finally, the structure of the Forgiveness schema was shown to be an additive one, regardless of the age of the participants.     

Sex,wage-earner status,occupational level,and job satisfaction

This study attempted to investigate the relationship between wage-earner status, occupational level, and job satisfaction. It was proposed that wage-earner status was a more important determinant of job satisfaction than sex. However, the findings of this study suggested that sex was a more important determinant of job satisfaction than wage-earner status, and occupational level was a better predictor of job satisfaction than either sex or wage-earner status.     

Uncertainty, entitativity, and group identification

Two studies examined the effects of self-uncertainty and ingroup entitativity on group identification. From uncertainty reduction theory (Hogg, 2000), it was hypothesized that people would identify most strongly with their group if they felt self-conceptually uncertain and the group was highly entitative. Study 1 was a field experiment (N = 114) in which the perceived entitativity of participants’ political party was measured, and self-uncertainty was primed (high vs. low). Study 2 was a laboratory experiment (N = 89) with ad hoc non-interactive groups. Uncertainty was primed as in Study 1, but perceived entitativity was manipulated. In both cases the dependent variable was a multi-item measure of group identification. The hypothesis was fully supported in both studies—participants identified more strongly when they were uncertain and the group was highly entitative. Implications of this research for the role of uncertainty and social identity in extremism, orthodoxy, and ideological belief systems are discussed.     

Speak, memory, or goodbye, Columbus

This article describes the vicissitudes in the career of a psychologist who entered graduate school almost immediately after the end of World War II at a time when the standards and definitions of appropriate training in clinical psychology were still being determined. Looking back at the developments in this career, a pattern of interests, unseen at the time, can now be detected. From investigating the influence of the subject-examiner relationship in the testing situation to the experimental study of psychoanalytic propositions, first using the Rorschach test and later by means of subliminal stimulation procedures, one central theme was the uncovering of disguises and hidden motives. A second major theme, much more explicit than the first, was the primacy of data over speculation.     

Friendship, proximity, and self-disclosure

Patterns of self-disclosure were explored by means of a questionnaire administered to pairs of roommates and hallmates (non-roommates living on the same floor) in freshman dormitories. It was predicted and found that friendship was more highly related to self-disclosure in intimate than in non-intimate topic areas, whereas proximity was more highly related to disclosure in non-intimate than in intimate areas. It was also found that friendship and intimate disclosure were more highly related among women than among men. These findings emphasize the interplay of personal, role-related, and environmental factors which underlie patterns of friendship and self-disclosure. They also point to the importance of viewing self-disclosure in differentiated terms, rather than as single monolithic entity. Other findings of both substantive and methodological interest are reported. For example, there was a strong tendency for respondents to overemphasize the degree to which their patterns of giving and receiving personal information were symmetrical. There was also a tendency for respondents to report giving more disclosure than they received in non-intimate areas, but not in intimate areas.     

Loneliness,eating, and body mass index in parent–adolescent dyads from the Family Life,Activity, Sun,Health, and Eating study

Loneliness is a salient risk factor for obesity, emotional eating, and poor diet. Because adolescents and parents are embedded within a family unit, their experiences of loneliness may be associated with both their own and one another's behaviors. To examine the extent to which parent and child loneliness predict body mass index (BMI) and eating in parents and adolescents, an actor–partner interdependence model of loneliness, eating, and BMI in adolescent–parent dyads was analyzed. There were actor effects among adolescents such that greater loneliness was positively associated with emotional eating and BMI‐z, and there was an actor effect among parents such that higher loneliness was positively related to emotional eating. There was a partner effect among adolescents such that greater parental loneliness was positively associated with adolescent emotional eating, and there was a partner effect among parents such that higher adolescent loneliness was positively associated with parental emotional eating. There were several actor–partner effects for loneliness and junk food in dyads with boys. Findings highlight the importance of dyadic models of loneliness in adolescent–parent dyads.     

INSTRUCTIONS,FEEDBACK, PRAISE,BONUS PAYMENTS,AND TEACHER BEHAVIOR1

The study was conducted within a training and demonstration center for teachers from several different school districts. The teachers staffing the center were employees of the host school district who volunteered to serve in the center. Unfortunately, these volunteers did not always use the program materials appropriately and therefore did not always provide clear models for visiting teachers. In particular, four of the volunteer teachers did not always instruct their students from the appropriate reading text, even when encouraged to do so by the principal of the school in which the center was located. Various procedures were employed to alter this situation. The experimenter, (associate director of the training and demonstration center) provided instructions, feedback, and praise regarding use of the appropriate reading text. These procedures had clear effects with only one teacher. Then, merit or bonus payments were provided for teachers who used the appropriate reading text for criterion periods of time; a procedure that was very effective with all four teachers. The problem worked on in this study is typical of those faced by workers in public institutions where change cannot be brought about by the researcher's authority. All teachers in the present study had the necessary skills to demonstrate accurately the prescribed program procedures, but they did not always do so until the bonus payment was used. Although the bonus payment procedure might be inappropriate in some school situations, the procedure could easily be adjusted to accommodate the established practices of many schools. For example, establishment of explicit performance criterion and use of in-service stipends for meeting criterion performance during school hours, rather than attendance at meetings after school, might well be comparably effective.     

Self-esteem, self-affirmation, and schadenfreude

In two studies we demonstrated that self-esteem has a negative relationship with schadenfreude toward a high achiever and that this relationship was mediated by the self-threat evoked by this high achiever. Moreover, we showed that this indirect relationship was contingent on an opportunity to affirm the self. When no self-affirmation opportunity was available, low self-esteem participants experienced a stronger self-threat when confronted with a high achiever, and this self-threat increased their schadenfreude, whereas this response was attenuated when they were given an opportunity to self-affirm. These findings indicate that the misfortunes of others can evoke schadenfreude because they provide people with an opportunity to protect or enhance their self-views.     

Depression,anxiety, hostility,and physical health

This study assessed the relationship of depression, anxiety, and hostility to physical health in a multicultural student population (N=106). When controlling for a variety of demographic and health risk factors (viz., age, sex, body mass, smoking, alcohol, salt, caffeine, and exercise), hostility, depression, and anxiety were related to higher reported incidences of physical symptoms and somatic illness. Depression and hostility had the strongest relationships with physical health, although the most striking single relationship was between depression and illness. Results suggest that it may be premature to focus our attention on hostility in research on the personality-illness relationship. They also suggest that the health behavior model of the relationship between personality and disease does not provide an adequate explanation, since negative affect was significantly associated with illness even when controlling for a variety of health risk factors. This work was supported, in part, by an intramural grant from the University of Hawaii, #R511.

Type A behavior in employed women: relation to work, marital, and leisure variables, social support, stress, tension, and health

Ninety-one women employed full-time were administered the Jenkins Activity Survey (JAS; Jenkins, Rosenman, & Zyzanski; 1974) and the Framingham Type A Scale (FTAS; Haynes, Levine, Scotch, Feinleib, & Kennel, 1978). Information concerning various work and nonwork-related variables was obtained via questionnaire or interview. Type A women had higher occupational levels and reported more demanding jobs and higher stress and tension than Type B women. Type A and B women did not differ in their reports of marital adjustment or in total hours spent in leisure activities. Type A behavior was related to both self-reported stress and tension--and for married women only, poorer self-reported physical health. Social support from various sources was not found to be related to Type A or Type B. Curiously, Type A was related to more reported stress and tension for women who felt they had many sources of support but not for women who did not perceive their having many sources of support.     

Trait anxiety, trait depression, worry, and memory

A study is reported which investigated the proposal that high trait anxiety is associated with a memory bias for worry themes. Forty-five participants were categorised as being high or low trait anxious on the basis of scores on the (Spielberger et al., 1983) (Manual for the State-Trait Anxiety Inventory (Form Y) (1983)). The participants were requested to rate a number of worry and non-worry statements for how much they generally thought about the issues represented by them. Analysis of the ratings given by the participants showed that low trait anxiety individuals thought about the non-worry items significantly more than worry items. The high trait anxiety participants, however, showed little or no difference in the amount of time spent thinking about worry and non-worry themes. In a subsequent free recall task of the statements it was observed that the low trait anxiety group recalled significantly more non-worry than worry items, whereas there was no such difference for the high trait group. It was also found that the degree of memory bias was related to both positive affectivity and trait anxiety. The implications of such findings are discussed.     

Personality,spirituality, suicide,and self-injury proneness among lesbian,gay, and bisexual adults

The present study sought to clarify gaps in current knowledge integrating personality, spirituality, and risk for suicide/self-harm among sample of 336 lesbian, gay, and bisexual community members. It was hypothesised that Neuroticism would positively predict, and Extraversion and Agreeableness would negatively predict, measures of suicide and self-injury proneness. Additionally, it was predicted that spirituality, defined as Spiritual Life Integration (SLI) and Social Justice Commitment, would interact with personality traits to attenuate risk for suicide and self-injury. Results supported the role of Neuroticism, and identified an unexpected predictor of Conscientiousness, at the main effect level. Moderation patterns were observed such that Agreeableness and Extraversion interacted with SLI to attenuate risk, such that high levels of each trait and high levels of spirituality were protective against suicide and self-injury proneness. Theoretical and practical implications with emphasis on counselling intervention implementation and future research are discussed.     

Neuroticism, extraversion, goals, and subjective well-being: Exploring the relations in young, middle-aged, and older adults

The positive association between intrinsic, as opposed to extrinsic, goal importance and Subjective Well-Being (SWB) is well-documented. However, less is known whether these associations are consistent across age groups and when simultaneously considering personality traits. Structural equation models conducted with young, middle-aged, and older adults indicated that neuroticism was negatively related to SWB across age groups, while extraversion and intrinsic goal importance held age-differential associations: Extraversion was related to SWB in the two younger age groups, whereas in older adults only an indirect effect emerged via intrinsic goal importance. Intrinsic goal importance was related to SWB among young and older adults but not among middle-aged adults. These results underscore the importance of age-differential associations in determinants of SWB.
