Illusion magnitude as a function of visual field exposure

Forty-eight right-handed subjects divided into four groups, each consisting of six males and six females, were employed in an investigation of cerebral hemispheric influence on the perception of tachistoscopically presented simultaneous and successive versions of the Mueller-Lyer figure. The simultaneous version exposed in the left visual field resulted in a larger effect than did right visual field exposures. The successive version exposed in the right visual field resulted in a larger illusion magnitude than it did in the left visual field. The magnitude of visual field differences in response to the successive version was greater than visual field differences found in response to the simultaneous version     

Introducing the living with illness group: A specialized treatment for patients with chronic schizophrenic conditions

This paper introduces a specialized psychotherapy/psychoeducational group treatment for patients with chronic psychotic symptoms who receive only partial benefit from psychotropic medications, psychotherapy, and milieu/activities therapy. The goal of the group is to assist patients to accurately identify the feelings, thoughts, and behaviors that are dysfunctional symptoms of their disability and then use the functional aspects of their brain as well as learned coping strategies to compensate for their disability. The group format, philosophy, procedures, and typical topics of discussion are detailed.The authors would like to thank Bruce Levine, Ph.D., and Terry Fujeoko, Ph.D., for their assistance with the initial formation of the group. Mr. Howe and Dr. Fujeoko originated the Living with Illness group and began the first group in 1985 at Waterbury Hospital Health Center, Waterbury, CT.     

Cyborg Identities and the Relational Web: Recasting 'Narrative Identity' in Moral and Political Theory

Current debates surrounding liberalism and communitarianism, modernity and postmodernity, ethical theory and narrative ethics fail to account for shifting foundations of personal identity in an increasingly computer-mediated era of human communication. This paper aims to examine some of the conceptual assumptions about identity and community which are being radically undermined by rapidly evolving information networks and are therefore in need of redefinition. Additionally, I argue for an expansion of the literary imagination to include virtual, coauthored fiction sites where exploration of personal identity will bear upon future ethical and political decision-making.     

Connecting the self to traumatic and positive events: links to identity and well-being

Self-event connections in autobiographical narratives help integrate specific episodes from memory into the life story, which has implications for identity and well-being. Previous research has distinguished differential relations between positive and negative self-event connections to psychological well-being but less research has examined identity. In this study, examining self-event connections in emerging adults’ narratives, 225 participants narrated a traumatic and an intensely positive experience and completed questionnaires assessing identity development and well-being. Participants who described more negative connections to self overall had higher psychological distress and identity distress, compared to those who described fewer negative connections. Participants who described positive connections to the self in traumatic events were more likely to have lower psychological distress, higher post-traumatic growth, and higher identity commitment, whereas positive connections in positive events was related to higher identity exploration and marginally higher post-traumatic growth. These findings contribute to a growing body of literature that suggests linking autobiographical memories to self can have differential effects on identity and well-being depending on the valence of the event and the connections made.     

Secondary attention-deficit/hyperactivity disorder following perinatal and childhood stroke: impact on cognitive and academic outcomes

This cross-sectional retrospective clinical research study examines a large group of children followed within a pediatric stroke program and a developmental attention-deficit/hyperactivity disorder (ADHD) clinic at the Hospital for Sick Children, between May 2004 and June 2016. All children with a history of stroke who participated in a neuropsychological assessment between the ages of 4 and 18 years were considered for inclusion. From a sample of 275 participants with a history of stroke, 36 children (13.1%) received a diagnosis of secondary ADHD. Children with secondary ADHD were younger at the time of stroke and more likely to be identified as having a presumed perinatal stroke and persistent seizures than children without secondary ADHD diagnoses. There were no differences in pattern of lesion, size, or laterality between children who developed secondary ADHD and those who did not. Children with secondary ADHD had the lowest scores across all cognitive and academic measures compared to children with stroke-only and developmental ADHD. Findings highlight the added risk of receiving a diagnosis of secondary ADHD following pediatric stroke. Implications for future research and directed intervention are discussed.     

Externalizing and personalizing biases in persecutory delusions: the relationship with poor insight and theory-of-mind

The presence of externalizing bias (EB) for negative events together with personalizing bias (PB) (a bias to blame others rather than circumstances) may jointly constitute a vulnerability to develop persecutory delusions (PDs). Whereas EB purportedly serves to defend a vulnerable self-concept by avoiding negative self-attributions and might therefore exacerbate poor insight, PB may reflect cognitive deficits, including theory-of-mind impairment. We investigated these proposals in 34 schizophrenic patients with a history of PDs and 21 healthy controls. Patients with moderate- to severe-PDs and patients without a current PD showed excessive EB which was, surprisingly, absent in patients with mild persecutory delusions (mild-PDs). That EB might wax and wane with fluctuating delusional intensity was interpreted in accord with a new dynamic model of attribution self-representation cycles. As predicted, EB exacerbated poor insight. However, counter to predictions, theory-of-mind impairment did not increase PB, which was marked in all participants, whether clinical or non-clinical; instead, theory-of-mind impairment was also correlated with poor insight. Our findings indicate multiple pathways to poor insight, one of which is a theory-of-mind difficulty, impairing the capacity to simulate other perspectives for the purpose of critically evaluating one's own beliefs and circumstances.     

Bring It On: Proactive Coping with Discrimination

We investigated proactive coping with discrimination among heavy women in both a high impact lab study (101 women) and a daily diary study (62 women). Heavy women assessed greater harm and fewer coping resources for discriminatory, as compared to non-discriminatory, hassles (Study 2). Primary appraisals of harm were important determinants of proactive coping, including primary control (attempts to change the environment) and secondary control (attempts to change the self to fit the environment) directed at discriminatory stressors (Studies 1 and 2). When heavy women used primary control coping efforts, they experienced positive interpersonal outcomes (Study 1) and less negative intrapersonal outcomes (Study 2). We discuss the benefits and limitations of engaging in proactive coping and suggest avenues for future research.

Media exposure, mood, and body image dissatisfaction: an experimental test of person versus product priming

In the current study, 138 college females were randomly assigned to four media exposure conditions based on the presence or absence of an attractive person (fashion model) and the presence or absence of an appearance-related product. Outcome measures consisted of visual analogue ratings of multiple body image and mood variables. The results revealed a significant main effect for person, indicating that the presence of a model increased levels of body dissatisfaction and negative mood. No product effect emerged and there was no significant interaction between person and product. These findings suggest that the appearance priming effect of media exposure on body dissatisfaction and mood is specific to a person stimulus, with no additional effect promoted by a generic appearance-relevant stimulus.     

Effects of Irrelevant Sounds on Phonological Coding in Reading Comprehension and Short term Memory

The effects of irrelevant sounds on reading comprehension and short-term memory were studied in two experiments. In Experiment 1, adults judged the acceptability of written sentences during irrelevent speech, accompanied and unaccompanied singing, instrumental music, and in silence. Sentences varied in syntactic complexity: Simple sentences contained a right-branching relative clause ( The applause pleased the woman that gave the speech ) and syntactically complex sentences included a centre-embedded relative clause ( The hay that the farmer stored fed the hungry animals ). Unacceptable sentences either sounded acceptable ( The dog chased the cat that eight up all his food ) or did not ( The man praised the child that sight up his spinach ). Decision accuracy was impaired by syntactic complexity but not by irrelevant sounds. Phonological coding was indicated by increased errors on unacceptable sentences that sounded correct. These error rates were unaffected by irrelevant sounds. Experiment 2 examined effects of irrelevant sounds on ordered recall of phonologically similar and dissimilar word lists. Phonological similarity impaired recall. Irrelevant speech reduced recall but did not interact with phonological similarity. The results of these experiments question assumptions about the relationship between speech input and phonological coding in reading and the short-term store.     

EQUATING INVERSE PROBABILITIES IN IMPLICIT PERSONALITY JUDGMENTS

Abstract— Meehl and Rosen (1955) observed that their colleagues tended to equate the sensitivity of a sign (its probability given a diagnostic category) with its predictive accuracy (the probability of the diagnostic category given the sign). Such equating of inverse probabilities implies ignoring base rates. Later, many researchers demonstrated such neglect in a number of experimental contexts involving hypothetical judgments; others have found some use of base rates—but only when base rates were supplied by the experimenter, in which case even irrelevant base rates influenced judgment. The present study tested for equating conditional probabilities in a context similar to the contexts involved in the initial observations—that is, subjects strove for accuracy rather than attempted to make good judgments about hypothetical problems, and the base rates were generated by the subjects themselves. Neglect of base rates was revealed by within-individual comparisons showing subjects equated inverse probabilities without equating the corresponding unconditional ones.
