Alibi believability: Corroborator certainty,cooperativeness and relationship with the defendant

Alibi believability can be affected by characteristics of the alibi corroborator, including the relationship between the defendant and corroborator, which has been studied extensively by researchers. The corroborator's certainty that they were together at the time of the crime may also influence alibi believability, but only a few studies have examined this. Another factor that may affect believability is the corroborator's cooperativeness with the police, which is yet to be studied in the alibi context. Online U.S. participants recruited from CloudResearch (N = 280) acted as mock jurors and evaluated a mock arson case where the defendant used an alibi defence. The alibi corroborator's relationship to the defendant (brother/neighbour), the certainty that they were together at the time (65%/100%) and cooperativeness with police (cooperative/uncooperative) were manipulated between participants. The participants were evenly split when it came to verdict (p > .05) but were more likely to vote guilty when the corroborator was a brother rather than a neighbour (p < .01) and when the brother was uncooperative versus cooperative (p < .05). As expected, alibis were more believable when they were corroborated by a neighbour rather than a brother and when the corroborator was 100% certain that they were together versus 65% certain (ps < .01). Alibis were also more believable when the corroborator cooperated than when he was uncooperative (p < .01). Cooperative (vs. uncooperative) corroborators led to more positive defendant and corroborator views on all six character trait measures (ps < .01). Implications and future directions are discussed.     

Effects of the coronavirus pandemic on perceived capitalization support provision and receipt

The coronavirus pandemic has influenced relationship dynamics due to heightened stress, increased isolation, and the need for social distancing. Prior work suggests receiving support for positive events (“capitalization support”) during this time could boost well-being, but only if it is provided in a manner that is active (involved) and constructive (supportive), as opposed to passive (uninvolved) and/or destructive (discouraging). Given the need for reduced social contact, we predicted the pandemic would make providing active, constructive support more challenging and might increase the frequency of passive support. We conducted two studies to explore how perceptions of capitalization methods may have shifted during the pandemic using an online participant pool (MTurk). Overall, we found that participants reported receiving significantly less active-constructive capitalization support and receiving more passive-constructive support during the pandemic (compared to pre-pandemic perceptions). In addition, we found that those who reported receiving and providing more active-constructive support tended to report more positive well-being outcomes. Interestingly, passive-constructive support was also associated with greater well-being for recipients (counter to prior research that has shown it associated with only costs). Overall, our data suggests that capitalization support perceptions are associated with well-being even during the pandemic, but methods of capitalization support perceived may have shifted during the pandemic.     

Eight-axis visual-field mapping for targets embedded in a homogeneous competing background

The binocular functional visual field for a detection task, with a peripherally presented target embedded in a homogeneous competing background, was mapped on 8 axes passing through the fixation point. The boundary of the field for each axis was based on the number of "correct" responses on the axis, where a "correct" response was defined in terms of the size of the error made by the subjects in estimating the target position. The visual fields for 6 subjects (4 men and 2 women) were very irregular in shape, and these were differences among subjects. The 8-axis area correlated highly with area based on only the horizontal and vertical axes but the latter area gave no indication of even gross irregularities in shape of the visual field.     

The relationship of gender discrepancy to eating disorder attitudes and behaviors

Few studies have investigated the possible influence of discrepancy between real and ideal perceptions of masculinity and femininity (i.e., gender discrepancy) on eating disorder behaviors and attitudes. Thus, this study examined the relationship of gender role discrepancy to bulimic and anorexic symptomatology, self-esteem, and concern about body shape in 178 female college students; the majority were Caucasian. Analyses revealed that women without a gender discrepancy reported fewer anorexic and bulimic symptoms, less concern with body shape, and higher self-esteem than those who were discrepant, particularly those desiring to be more masculine. Results are discussed with respect to current discrepancy theory, and directions for future research are provided.     

Generating multivariate data from nonnormal distributions: Mihal and Barrett revisited

An algorithm described by Graybill (1969) factors a population correlation matrix, R, into an upper and lower triangular matrix, T and T′, such that R=T′T. The matrix T is used to generate multivariate data sets from a multinormal distribution. When this algorithm is used to generate data for nonnormal distributions, however, the sample correlations are systematically biased downward. We describe an iterative technique that removes this bias by adjusting the initial correlation matrix. R, factored by the Graybill algorithm. The method is illustrated by simulating a multivariate study by Mihal and Barrett (1976). Large-N simulations indicate that the iterative technique works: multivariate data sets generated with this approach successfully model both the univariate distributions of the individual variables and their multivariate structure (as assessed by intercorrelation and regression analyses).     

Innovative Community Services for Rape Victims: An Application of Multiple Case Study Methodology

A qualitative multiple case study design was used to examine communities across the United States that have developed coordinated community-based programs to assist rape victims. Previous studies have suggested that coordinated community programs help victims obtain needed resources and services. This study provided a follow-up examination of how and why these programs are helpful to rape victims. In-depth interviews were conducted with rape victim advocates, rape crisis center directors, police officers, prosecutors, doctors, nurses, and rape survivors from 22 communities with coordinated programs. A comparison sample of 22 communities with fewer coordinated programs was also obtained. Results indicated that the high coordination communities had three types of programs to address sexual assault: coordinated service programs, interagency training programs, and community-level reform groups. Although not all of these programs directly address service delivery for rape victims, they help create a community culture that is more responsive to victims' needs. The research team and participants developed an explanatory model of why these program are effective in addressing rape victims' needs. This model hypothesizes that coordinated programs reflect an understanding of the multiple contexts of service delivery and embody that knowledge in services that are consistent with victims' needs. Narrative data from the interviews with service providers and rape survivors are used to develop and support this model.     

HabitWorks: Development of a CBM-I Smartphone App to Augment and Extend Acute Treatment

The month following discharge from acute psychiatric care is associated with increased risk of relapse, rehospitalization, and suicide. Effective and accessible interventions tailored to this critical transition are urgently needed. Cognitive bias modification for interpretation (CBM-I) is a low-intensity intervention that targets interpretation bias, a transdiagnostic process implicated in the development and maintenance of emotional disorders. We describe the development of a CBM-I smartphone app called HabitWorks as an augmentation to acute care that extends through the high-risk month postdischarge. We first obtained input from various stakeholders, including adults who had completed partial hospital treatment (patient advisory board), providers, CBM experts, and clinic program directors. We then iteratively tested versions of the app, incorporating feedback over three waves of users. Participants were recruited from a partial hospital program and completed CBM-I sessions via the HabitWorks app while attending the hospital program and during the month postdischarge. In this Stage 1A treatment development work, we obtained preliminary data regarding feasibility and acceptability, adherence during acute care, and target engagement. Pilot data met our a priori benchmarks. While adherence during acute treatment was good, it decreased during the postacute period. Qualitative feedback was generally positive and revealed themes of usability and helpfulness of app features. Participants varied in their perception of skill generalization to real-life situations. The feasibility and acceptability data suggest that a controlled trial of HabitWorks is warranted.     

Inserting mastered targets during error correction when teaching skills to children with autism

Research has identified a variety of effective approaches for responding to errors during discrete‐trial training. In one commonly used method, the therapist delivers a prompt contingent on the occurrence of an incorrect response and then re‐presents the trial so that the learner has an opportunity to perform the correct response independently. Some authors recommend inserting trials with previously mastered targets between the prompted response and opportunities to respond independently, but no studies have directly examined the benefits of this approach. In this study, we manipulated the placement of trials with mastered targets during discrete‐trial training to compare the effectiveness of error correction with and without this recommended insertion procedure. Four children with autism participated, and each was taught 18 targets across 3 target sets. Results indicated that embedding trials with mastered targets into error correction may not confer benefits for most children and that doing so may lead to less efficient instruction.     

Fading Affect Bias in the Philippines: Confirmation of the FAB in Positive and Negative Memories but Not for Death Memories

Emotions associated with memories for the loss of a loved one and for negative events in general decrease in intensity more than memories associated with positive events, a phenomenon known as the fading affect bias (FAB). We tested whether FAB was cross‐culturally evident by collecting positive, negative, and memories for the deaths of loved ones from Filipinos. Memories were coded as violent/nonviolent and resolved/unresolved, and we predicted that resolved memories should show greater fading and that affective details should be lower in those memory accounts. FAB analyses revealed that negative affective intensity faded while positive affect remained constant, supporting FAB for positive and negative memories. However, there was no evidence of FAB in Filipinos' death memories. Filipinos' positive memories were distributed from the period of the reminiscence bump and focused on themes of childbirth and marriage, while negative and death memories did not cluster at any period of life.Copyright © 2015 John Wiley & Sons, Ltd.     

The effect of visualization on visual search performance

Striking results recently demonstrated that visualizing search for a target can facilitate visual search for that target on subsequent trials (Reinhart et al. 2015). This visualization benefit was even greater than the benefit of actually repeating search for the target. We registered a close replication and generalization of the original experiment. Our results show clear benefits of repeatedly searching for the same target, but we found no benefit associated with visualization. The difficulty of the search task and the ability to monitor compliance with instructions to visualize are both possible explanations for the failure to replicate, and both should be carefully considered in future research exploring this interesting phenomenon.
