Visual search for a motion singleton among coherently moving distractors

In the current study, we tested whether search for a visual motion singleton presented among several coherently moving distractors can be more efficient than search for a motion stimulus presented with a single distractor. Under a variety of conditions, multiple spatially distributed and coherently moving distractors facilitated search for a uniquely moving target relative to a single-motion-distractor condition (Experiments 1, 3, and 4). Color coherencies among static distractors were not equally effective (Experiments 1 and 2). These results confirm that humans are highly sensitive to antagonistically directed motion signals in backgrounds compared with spatially more confined regions of visual images.     

Words and Wards: A Model of Reflective Writing and Its Uses in Medical Education

Personal, creative writing as a process for reflection on patient care and socialization into medicine ("reflective writing") has important potential uses in educating medical students and residents. Based on the authors' experiences with a range of writing activities in academic medical settings, this article sets forth a conceptual model for considering the processes and effects of such writing. The first phase (writing) is individual and solitary, consisting of personal reflection and creation. Here, introspection and imagination guide learners from loss of certainty to reclaiming a personal voice; identifying the patient's voice; acknowledging simultaneously valid yet often conflicting perspectives; and recognizing and responding to the range of emotions triggered in patient care. The next phase (small-group reading and discussion) is public and communal, where sharing one's writing results in acknowledging vulnerability, risk-taking, and self-disclosure. Listening to others' writing becomes an exercise in mindfulness and presence, including witnessing suffering and confusion experienced by others. Specific pedagogical goals in three arenas-professional development, patient care and practitioner well-being - are linked to the writing/reading/listening process. The intent of presenting this model is to help frame future intellectual inquiry and investigation into this innovative pedagogical modality.     

Spouses' attributions for helping: the effects of styles of help-seeking,self-serving bias,and sex

This paper examines the effects of (a) how clearly the desire for help is presented, (b) self-serving bias, and (c) sex differences on the source of the cause of helping happening (or not) that spouses attribute to a potential helper. In two studies, a total of 138 couples imagined situations in which a person wanted his or her spouse to do a chore. How clearly the desire for help was expressed, whether help was given, and whether it was the participant or the spouse who was expected to help were manipulated. The participants reported their attributions for the cause of helping (or not) to themselves and the spouse on visual analog scales. There was strong support for a proposed interaction between how clearly the desire for help was expressed and whether help was given in predicting spouses' attributions. No support was obtained for a predicted self-serving bias or for a suggestion that men make more self-enhancing attributions than women, the findings were instead congruent with a relationship-enhancing bias. The findings are discussed in terms of the context of housework.     

Lateralized perceptual organization deficits on the global-local task in schizotypal personality disorder

Right and left hemisphere contributions to perceptual organization functions were examined using a divided-attention version of the global-local task in a sample of 21 unmedicated participants diagnosed with schizotypal personality disorder (SPD) and 20 controls. The SPD participants showed an abnormal global processing advantage. When the visual angle of the hierarchical stimuli was increased from 3 degrees to 9 degrees, the controls showed an increasing local processing advantage, but the SPD participants continued to show an abnormal global processing advantage. These findings suggest a local processing deficit on divided-attention versions of the global-local task in schizophrenia spectrum disorders. Female SPD participants, who had less severe interpersonal deficit symptoms, showed a more abnormal global processing advantage. Hemispheric and processing resource mechanisms that might explain these findings are discussed.     

Traumatic impact predicts long-term memory for documented child sexual abuse

Prospective studies of adults' memories of documented child sexual abuse (CSA) reveal that the majority of individuals remember their victimization. However, the accuracy of these memories has rarely been investigated scientifically. The present study examined predictors of memory accuracy and errors 12 to 21 years after abuse ended for individuals with legal experiences resulting from documented CSA. Severity of posttraumatic stress disorder (PTSD) symptomatology was positively associated with memory accuracy. However, individuals nominating CSA as their most traumatic life event exhibited relatively accurate memory regardless of indicators of PTSD. Predictors of memory errors were also identified (e.g., less maternal support). These results indicate that, in addition to understanding the role of traditional cognitive factors, understanding an event's traumatic impact is important for predicting the accuracy of long-term memory for reported CSA.     

Lexical information drives perceptual learning of distorted speech: evidence from the comprehension of noise-vocoded sentences

Speech comprehension is resistant to acoustic distortion in the input, reflecting listeners' ability to adjust perceptual processes to match the speech input. For noise-vocoded sentences, a manipulation that removes spectral detail from speech, listeners' reporting improved from near 0% to 70% correct over 30 sentences (Experiment 1). Learning was enhanced if listeners heard distorted sentences while they knew the identity of the undistorted target (Experiments 2 and 3). Learning was absent when listeners were trained with nonword sentences (Experiments 4 and 5), although the meaning of the training sentences did not affect learning (Experiment 5). Perceptual learning of noise-vocoded speech depends on higher level information, consistent with top-down, lexically driven learning. Similar processes may facilitate comprehension of speech in an unfamiliar accent or following cochlear implantation.     

Viewing oneself during synchronous online learning increases appearance anxiety and decreases memory for lecture content

In response to the COVID-19 pandemic, instructors began using online learning platforms to offer live remote instruction (e.g., Zoom), which allow students to view themselves in real-time (i.e., self-view). The present research examined whether having students keep their cameras on, relative to cameras off, during a live online lecture would increase anxiety and reduce learning. In both Experiment 1a (small group setting) and Experiment 1b (large group setting), students in the camera-on condition did not report greater state anxiety, nor was anxiety associated with lower performance on an immediate multiple-choice exam. Experiment 2 specifically examined the effect of self-view and if appearance anxiety (rather than state anxiety) might mediate the relationship between camera use and test performance. Results indicate that participants viewing themselves reported significantly higher appearance anxiety, and that higher appearance anxiety was related to decreased learning. These findings suggest that viewing oneself may uniquely contribute to heightened appearance anxiety and may reduce memory for content when learning synchronously online.     

FROM THE SENSES TO SENSE: THE HERMENEUTICS OF LOVE

Abstract. Drawing on philosophy, theology, comparative religion, spirituality, Holocaust studies, physics, biology, psychology, and personal experience, I argue that continued human existence depends on our willingness to reject nihilism–not as an expedient "noble lie" but because faith in a meaningful cosmos and the power of love is at least as validly grounded in human experience as insistence on cosmic indifference and ultimate futility. I maintain that hope will free us to develop nonimperialistic methods of bridging cultural differences by forming a mutually intelligible vocabulary that celebrates diversity, enters the worlds of others in respectful dialogue, and fosters a postmechanistic, organic, ecological, holistic, dynamic, interactive, open-ended model of reality. I lay the foundation for a "hermeneutics of love" to complement Paul Ricoeur's "hermeneutics of suspicion" and invite speculation on the ways science, technology, and society would be transformed if those "glasses of friendship" were widely applied.     

TRAINING MILDLY HANDICAPPED PEERS TO FACILITATE CHANGES IN THE SOCIAL INTERACTION SKILLS OF AUTISTIC CHILDREN

We evaluated the effects of a peer-training strategy, consisting of direct prompting and modeling, on the occurrence and duration of interactions between autistic students and nonautistic peer-trainers. Data were obtained in both training and generalization settings. The results of a multiple-baseline design across students demonstrated that: (a) the direct prompting procedure produced immediate and substantial increases in the occurrences and durations of positive social interactions between the peer-trainers and autistic students; (b) these increases were maintained across time at levels above baseline during subsequent free-play probes; (c) these findings were judged by teachers to be socially valid; (d) untrained peers increased their interactions with the autistic students in three of the four groups; (e) generalization of behavior change across settings occurred only after specific programming; and (f) interactions between untrained peers and peer-trainers decreased following training. Variables that may account for the results and the implications of these findings for peer-mediated interventions are discussed.
