Productivity and uniqueness in continued word association as a function of subject creativity and stimulus properties

Ninety-six male and 44 female college students gave written continued associations for 2 minutes to each of 24 stimulus words and then completed the Remote Associates Test and the Revised Art Scale No significant relationship was found between the creativity measures for either sex Few relationships, differing for males and females, were found between the creativity measures and associative productivity or uniqueness Productivity and uniqueness were found to be substantially related, and common responses occurred earlier in time than unique responses The properties of the stimulus words (frequency, form class, and slope of associative hierarchy) had marked effects on response productivity and uniqueness The study confirms the strong impact of stimulus properties on associative productivity and demonstrates similar effects on uniqueness The creativity data, yielding weaker and less consistent relationships, are in keeping with a specificity theory but lend only limited support to Mednick's associative hypotheses.     

Increased conformity to a fellow deviant as a function of prior deviation

A subject was induced to publically report his opinions on a variety of issues. A group of confederates disagreed with the subject; one confederate agreed with him. Thus, the subject deviated from the majority of the group, but received social support from one other individual. Each subject was then paired with one individual from the previous group, and regardless of his pairing, was subjected to a constant amount of conformity pressure from the confederate on a new set of judgments. Deviant subjects conformed more to the confederate who had previously given them social support than they did to a previous majority member. This increased conformity was found in two studies, (1) females judging physical realities and, (2) males reporting their opinions on attitudinal issues. Ratings taken in the second study demonstrated that the deviant subject felt increased liking for and similarity to the confederate who initially provided him with social support, but comparisons between various experimental groups indicated conformity to a confederate was not completely predictable from the subject's liking for that confederate. Instead, conformity was greatest following an experience of deviation from the majority.     

Preference for signalled reinforcement

Key pecking was reinforced on a two-component multiple schedule. A variable-interval schedule controlled reinforcement in both components. During one component, access to reinforcement was preceded by a tone; in the other component, a standard unsignalled schedule was in effect. After performance stabilized, subjects were given a choice between the signalled and unsignalled schedules. They were placed in the chamber with the unsignalled schedule in effect on the right key. A single response on the left, or changeover, key produced the signalled schedule for 1 min. Both pigeons in Experiment I pecked the changeover key at a rate sufficient to remain under the signalled schedule for over 90% of the session. Removing and reintroducing the tone demonstrated that the changeover-key responses were due to the occurrence of the tone. In Experiment II, when pecking the changeover key produced the unsignalled schedule, pecking the changeover key declined. The results may be explained either in terms of Hendry's information hypothesis or as escape from an intermittent positive reinforcement schedule.     

The quail, Coturnix coturnix, as a laboratory animal

The quail, Coturnix coturnix, is small, gentle, hardy, adaptable, easy to house, and economical to maintain. Wetherbee and Jacobs (1960) call it the “Drosophila of the avian laboratory,” and yet this charming bird is virtually unknown to the psychological laboratory. Our preliminary investigations show that the pecking operant is readily conditioned and that little or no deprivation is necessary to maintain behavior with food as a reinforcer. Visual and temporal discriminations were very quickly made. Our observations suggest that the social behavior of these birds might be a fruitful area for psychological study. On the basis of our somewhat limited observations, we believe that C. coturnix should prove a useful experimental animal for comparative studies, for basic research in learning, motivation, and perhaps social behavior, and for teaching the analysis of behavior in demonstrations and laboratory courses.     

Emotional Reactions and Moral Judgment: The Effects of Morally Challenging Interactions in Military Operations

This study explores the association between different types of morally challenging interactions during military deployment and response strategies (e.g., moral justification), as well as the mediating role of moral emotions. Interviews with Dutch servicemen who participated in military operations (e.g., in Afghanistan, Angola; N = 45) were content coded. We found a relationship between local-cultural and team-related interactions and moral justification; these effects were mediated by other-condemning emotions. Similarly, other-condemning emotions mediated the relationship between local-cultural interactions and relativism. This study points at the importance of other-condemning emotions in shaping military reactions to frequently occurring morally challenging interactions.     

Mentoring Relationship Closures in Big Brothers Big Sisters Community Mentoring Programs: Patterns and Associated Risk Factors

Previous research suggests that early mentoring relationship (MR) closures may have harmful consequences for the health and well‐being of youth participating in community‐based mentoring programs. However, knowledge of the factors that lead some MRs to close early has been slow to emerge. This study examined patterns and correlates of early versus on‐time MR closures among 569 youth participating in Big Brothers Big Sisters community mentoring programs. Thirty‐four percent of youth experienced an early MR closure prior to the end of the program's 12 month period of commitment. The probability of closure was highest at 12 months into the MR. Early closures were positively associated with youth gender (girls), behavioral difficulties, and match determination difficulties. Early and on‐time closures were associated with youth extrinsic motives for joining the program. Early MR closures were negatively associated with youth perceptions of parent emotional support, parent social support, high quality MR, weekly contact in MR, and parent support of the MR. Implications for programming are discussed.     

A pilot study of women’s affective responses to common and uncommon forms of aerobic exercise

Objective: To test the extent to which participants exposed to an uncommon versus common exercise stimulus would result in more favourable affect at post-task.

Design: Experimental design. Participants (N = 120), American women aged 18–45 years, were randomly assigned to complete 30-min of either the uncommon (HOOP; n = 58) or common (WALK; n = 62) exercise stimulus.

Main outcome measures: Self-reported affect and intentions for future exercise were measured before and after the 30-min exercise bout.

Results: Analyses of covariance were run to compare post-task affect across the HOOP and WALK conditions. At post-task, participants assigned to HOOP reported more positively valenced affect, higher ratings of positive activated affect, lower ratings of negative deactivated affect, and stronger intentions for future aerobic exercise compared to participants assigned to WALK.

Conclusions: Participants who completed an uncommon bout of aerobic exercise (HOOP) reported more favourable affect post-exercise, as well as stronger intentions for future exercise, compared to participants who completed a common bout of aerobic exercise (WALK). Future work using a longitudinal design is needed to understand the relationships between familiarity with an exercise stimulus, affective responses to exercise, motivation for future exercise behaviour and exercise maintenance over time.
