A Survey of Dynamic Principles Governing Memory

A triadic coalition game was structured as an achievement-oriented situation by inclusion of a skill-based game task. Deductions regarding coalition partner choices were derived from Atkinsons' model of achievement motivation with the expectation that achievement-oriented players (Ms < Maf) would prefer moderate-risk strategy options while failure-avoidant players (Maf < Ms) would avoid moderate-risk strategies.

Observation was made of the coalition partner preferences of 126 college sophomore males and females who played the game in same-sex triads. The Ss were categorized into motive configuration groups on the basis of scores derived from the Test of Insight and the Test Anxiety Questionnaire.

The results were supportive of the hypotheses, since the Ms < Maf group chose moderate-risk coalition options more frequently than did the Maf < Ms group. By contrast the Maf < Ms group chose low-risk strategies and tended to avoid moderate-risk coalition options. While other coalition-game studies have shown differences in strategy behavior between males and females, sex differences did not occur in the present game. The lack of sex differences was explained by the high level of concern for winning among members of both sexes generated by the achievement nature of the game task.

An interresponse time analysis of variable-ratio punishment

An interresponse time analysis was used to study the effects of variable-ratio punishment schedules on the temporal pattern of reinforced responding. Twelve pigeons responded on a baseline variable-interval schedule of food reinforcement. A variable-ratio ten schedule of electric shock punishment was then introduced. The shock intensity was systematically increased to the highest intensity at which responding could be maintained. At this intensity, the mean variable-ratio value was increased and then decreased. Variable-ratio punishment resulted in an increased relative frequency of very short unreinforced interresponse times (response bursting). Increased response bursting accounted for instances of response rate facilitation. In addition, shock was followed by interresponse times of decreasing mean length over the first several responses after shock.     

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.     

On the Representation of Strong and Weak Attitudes About Policy in Memory

A priming paradigm was used to explore the representation of attitudes about government policies in memory. Participants performed pairs of tasks in quick succession. The focal tasks involved evaluating a policy or thinking of one of its consequences. The results showed that thinking of a consequence of a policy speeded up its subsequent evaluation, regardless of whether the participant held a strong or weak attitude about the policy. Evaluating the policy speeded up thinking of one of its consequences for strong attitudes but not for weak ones. In general, it took participants longer to think of a consequence of a policy than to evaluate it. The implications of these results for existing views of the representation of attitudes in memory are discussed.     

Tendency to commit traffic violations and presence of passengers in the car

The present study examined whether the tendency to commit traffic violations differed when drivers were with and without the presence of other persons in the car. One thousand and eight drivers were observed by the road side. The data registered by the observers included estimated age of the driver and the passengers, sex of the driver and number of passengers. Four dependent variables were registered for each driver, which are, wearing seatbelt, signaling, using hand-held cellular phone and keeping the distance from the vehicle in front. It has been found that for both males and females, old and young, a greater proportion of drivers who were alone committed traffic violations as compared to drivers who were not alone. These results are discussed in relation to social influences on drivers and allow insight into how the presence of passengers has an impact on driver behavior and traffic safety.     

Multimodal reflection for creative facilitators: an approach to improving self-care

Creative and arts-based facilitators who work in the area of supporting others, such as youth workers, educators, counsellors and therapists, often do not prioritise their own well-being and self-care. This paper explores a study that focused on the utility of multimodal reflection for sustainable as well as satisfying practice for creative facilitators. Participants in the study were involved in a trial 10-week reflective programme called Stepping Outside the Circle. This programme was part of a larger research project that sought to understand the professional and reflective practices of creative facilitators, a term used within the study to encompass practitioners who use arts (both performative and visual) interventions to work within a variety of therapeutic and educational settings. During the programme, participants drew on their own personal knowledge of the disciplines in which they worked and reflected in and on this practice both professionally and personally. They also collaboratively supported each other through the process. We argue that engagement in multimodal reflection shared with others, particularly for creative facilitators, is integral for purposeful and effective self-care practice.     

Additivity of semantic and phonological effects: Evidence from speech production in Mandarin

A number of previous studies using picture–word interference (PWI) tasks conducted with speakers of Western languages have demonstrated non-additive effects of semantic and form overlap between pictures and words, which may indicate underlying non-discrete processing stages in lexical retrieval. The present study used Mandarin speakers and presented Chinese characters as distractors. In two experiments, we crossed semantic relatedness with “pure” phonological (i.e., orthographically unrelated) relatedness and found statistically additive effects. In a third experiment, semantic relatedness was crossed with orthographic overlap (phonological overlap was avoided), and once again we found an additive pattern. The results are discussed with regard to possible cross-linguistic differences between Western and non-Western languages in terms of phonological encoding, as well as concerning the locus of relatedness effects in PWI tasks.     

Coaction and upward social comparison reduce the illusory conjunction effect: Support for distraction-conflict theory

This article proposes an integration of Festinger’s (1954) social comparison theory and Baron’s (1986) distraction-conflict theory of the social facilitation-inhibition effect, which successfully predicts attentional focusing in coaction when social comparison represents a distraction. Two experiments confronted participants with the illusory conjunction task (Treisman, 1998), where illusions occur because of the lack of attentional processing of central cues. If coaction, like upward comparison, is distracting and thereby enhances the attention allocated to central cues (here the target’s features) at the expense of peripheral cues (here distractors), then a reduction should be found in the illusions. Experiment 1 indeed showed a lower rate of conjunctive errors under upward comparison than under downward comparison. Experiment 2 specified that this effect was due to downward comparison effectively reducing distraction, with upward comparison only maintaining it, as compared to mere coaction.
