The influence of multiple trials and computer-mediated communication on collaborative and individual semantic recall

Collaborative inhibition is a phenomenon where collaborating groups experience a decrement in recall when interacting with others. Despite this, collaboration has been found to improve subsequent individual recall. We explore these effects in semantic recall, which is seldom studied in collaborative retrieval. We also examine “parallel CMC”, a synchronous form of computer-mediated communication that has previously been found to improve collaborative recall [Hinds, J. M., & Payne, S. J. (2016). Collaborative inhibition and semantic recall: Improving collaboration through computer-mediated communication. Applied Cognitive Psychology, 30(4), 554–565]. Sixty three triads completed a semantic recall task, which involved generating words beginning with “PO” or “HE” across three recall trials, in one of three retrieval conditions: Individual–Individual–Individual (III), Face-to-face–Face-to-Face–Individual (FFI) and Parallel–Parallel–Individual (PPI). Collaborative inhibition was present across both collaborative conditions. Individual recall in Recall 3 was higher when participants had previously collaborated in comparison to recalling three times individually. There was no difference between face-to-face and parallel CMC recall, however subsidiary analyses of instance repetitions and subjective organisation highlighted differences in group members' approaches to recall in terms of organisation and attention to others' contributions. We discuss the implications of these findings in relation to retrieval strategy disruption.     

Physical Abuse Victimization and Violence in the Transition to Adulthood: The Mediating Role of Alcohol and Drug Use

In the present paper we examine the association between physical abuse victimization in childhood and violent criminal behavior in the transition from adolescence to adulthood (TAA). Of central interest is whether that association is indirect, through the impact of abuse victimization on alcohol and drug use. We employ a statistical test for indirect effects, using a design that also applies Savage and Wozniak’s (2016) “differential etiology of violence” standard. The data suggest that the effect of physical abuse on violence in the TAA is partially indirect, mediated by alcohol and drug use. A control for nonviolent offending is applied to build confidence that the dynamic between abuse victimization and substance use is a differential predictor of violence.     

Intrusive and avoidant ideation among females pursuing infertility treatment

Abstract

It was shown that infertility and its treatment constitute a stressful experience for women, reflected particularly in disturbing intrusive ideation about the stress source. Infertility patients reported levels of intrusive ideation significantly higher than routine gynecologic patients and not significantly different from levels of psychiatric outpatients being treated for stress reactions to traumatic events. Intrusive ideation also predicted the degree of self-reported infertility-specific distress and dysfunction, further clarifying the key role of such ideation in the experience. Finally, as hypothesized, the frustration level of the treatment experience (as indexed by the number of infertility treatment methods attempted) predicted avoidant ideation. Implications for managing the psychological distress and disruption associated with the infertility treatment experience were discussed.     

Perceptions of the roles of behaviour and genetics in disease risk: Are they associated with behaviour change attempts

Objective: We examined selected survivor characteristics to determine what factors might moderate the response to two psychosocial interventions.

Design: Seventy-one prostate cancer survivors (PCSs) were randomly assigned to either a telephone-delivered health education (THE) intervention or a telephone-delivered interpersonal counselling (TIP-C) intervention.

Measures: Psychological quality of life (QOL) outcomes included depression, negative and positive affect, and perceived stress.

Results: For three of the psychological outcomes (depression, negative affect and stress), there were distinct advantages from participating in THE. For example, more favourable depression outcomes occurred when men were older, had lower prostate specific functioning, were in active chemotherapy, had lower social support from friends and lower cancer knowledge. Participating in the TIP-C provided a more favourable outcome for positive affect when men had higher education, prostate specific functioning, social support from friends and cancer knowledge.

Conclusion: Unique survivor characteristics must be considered when recommending interventions that might improve psychological QOL in PCSs. Future research must examine who benefits most and from what components of psychosocial interventions to enable clinicians to recommend appropriate psychosocial care.     

Response rate and reinforcement rate in Pavlovian conditioning

Four experiments used delay conditioning of magazine approach in rats to investigate the relationship between the rate of responding, R, to a conditioned stimulus (CS) and the rate, r, at which the CS is reinforced with the unconditioned stimulus (US). Rats were concurrently trained with four variable-duration CSs with different rs, either as a result of differences in the mean CS-US interval or in the proportion of CS presentations that ended with the US. In each case, R was systematically related to r, and the relationship was very accurately characterized by a hyperbolic function, R = Ar/(r +c). Accordingly, the reciprocal of these two variables-response interval, I (= 1/R), and CS-US interval, i (= 1/r) - were related by a simple affine (straight line) transformation, I = mi+b. This latter relationship shows that each increment in the time that the rats had to wait for food produced a linear increment in the time they waited between magazine entries. We discuss the close agreement between our findings and the Matching Law (Herrnstein, 1970) and consider their implications for both associative theories (e.g., Rescorla & Wagner, 1972) and nonassociative theories (Gallistel & Gibbon, 2000) of conditioning.

The relationship between multisensory integration and IQ in children

It is well accepted that multisensory integration has a facilitative effect on perceptual and motor processes, evolutionarily enhancing the chance of survival of many species, including humans. Yet, there is limited understanding of the relationship between multisensory processes, environmental noise, and children's cognitive abilities. Thus, this study investigated the relationship between multisensory integration, auditory background noise, and the general intellectual abilities of school-age children (N = 88, mean age = 9 years, 7 months) using a simple audiovisual detection paradigm. We provide evidence that children with enhanced multisensory integration in quiet and noisy conditions are likely to score above average on the Full-Scale IQ of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). Conversely, approximately 45% of tested children, with relatively low verbal and nonverbal intellectual abilities, showed reduced multisensory integration in either quiet or noise. Interestingly, approximately 20% of children showed improved multisensory integration abilities in the presence of auditory background noise. The findings of the present study suggest that stable and consistent multisensory integration in quiet and noisy environments is associated with the development of optimal general intellectual abilities. Further theoretical implications are discussed.     

Severe and nonsevere events in first onsets versus recurrences of depression: evidence for stress sensitization

Overall, research has evidenced support for Post's (1992) model, which asserts that the 1st episode of depression is more likely to be associated with severe life events than are subsequent episodes. In spite of this, there are significant gaps in the understanding of the stress-depression association. This study aimed to address three gaps by (a) identifying the explanatory model underlying the association (stress sensitization vs. stress autonomy), (b) elucidating how the role of stress changes with successive episodes, and (c) examining the role of nonsevere events. The impact and occurrence of severe and nonsevere events in a 5-year longitudinal study of late-adolescent women were examined using Cox regression models. Overall, we found support for the stress sensitization model over the stress autonomy model. Specifically, the impact of nonsevere (but not severe) events was greater in individuals with a history of depression compared with those with no history of depression. In addition, the occurrence of severe (but not nonsevere) events was greater for 1st onsets than recurrences. These effects were modified by event independence. The results were discussed in terms of the underlying mechanisms of the stress-depression association and future directions for research were elaborated.     

Acute mood responses to a 15-minute long walking session at self-selected intensity: effects of an experimentally-induced telic or paratelic state

In the present controlled experiment, we examine the influence of opposite states of mind (the "telic" vs. "paratelic" state) on mood response to a 15 min long walk at self-selected pace. Fifty-five first-year students were randomized to a telic (n = 22) or paratelic (n = 33) motivational environment. These opposed motivational environments were created using established reversal theory based procedures to induce the telic versus paratelic state. More than 90% of participants walked within a motivational state corresponding to the environment they were allocated. No significant mood changes (neither positive, nor negative) occurred pre- to postexercise in participants who walked with the telic state operative (p > .05). This has important implications when considering the use of exercise to relieve depression in clinical populations. Also, our findings shed new light on the reasons why not all individuals respond in the same way to moderate exercise. Practically, these results suggest that motivational state should be considered to optimize the mood enhancing effects of aerobic exercise.     

A hit-and-miss investigation of asymmetries in wheelchair navigation

In contrast to the leftward inattention caused by right parietal damage, normal brain function shows a subtle neglect of the right and left sides in peripersonal and extrapersonal space, respectively. This study explored how these attentional biases cause healthy individuals to collide with objects on the right. In Experiment 1, participants navigated manual and electric wheelchairs through a narrow doorway. More rightward collisions were observed for the electric, but not the manual, wheelchair. Experiment 2 demonstrated that the rightward deviation for electric wheelchairs increased for wider doorways. Experiment 3 established that the rightward deviation is not the result of task-related vestibular input, using a remote control device to operate the wheelchair. The rightward deviation persisted in Experiment 4 when the doorway was removed, suggesting that the bias is the result of a mis-bisection of space. In Experiment 5, the rightward bias was replicated using an electric scooter, which is steered using handlebars. Finally, Experiment 6 required participants to point to the middle of the doorway, using a laser, before moving the scooter. Rightward mis-bisection was observed in both conditions. Rightward mis-bisection of lines in extrapersonal space provides the most parsimonious explanation of the rightward collisions and deviations.     

The Role of Culture,Workgroup Membership,and Organizational Status on Cooperation and Trust: An Experimental Investigation

We examined how interactions among participants' cultural backgrounds (e.g., Australian vs. Singaporean) and multiple subgroups (e.g., cultural group membership, workgroup membership, organizational status) affect trust and cooperation in the workplace. University students (120 Australians, 120 Singaporeans) responded to hypothetical scenarios of cooperation and trust in the workplace. The results indicated that, for both Australians and Singaporeans, trust and cooperation were more strongly influenced by workgroup membership and organizational status than by cultural group membership. Participants trusted and cooperated more with work in‐group members than with work out‐group members, and trusted and cooperated more with superiors than with peers. Theoretical implications are discussed.
