The Effect of Inhibition of Return on Lexical Access

Abstract—Inhibition of return refers to a bias against returning attention to a location or object that has been recently attended. Recent research has shown that inhibition of return can be found not only in simple detection tasks, but also in tasks requiring relatively simple discrimination judgments. The present experiments examined whether inhibition of return occurs in tasks that require complex discriminations such as lexical decision and categorization tasks. Not only was inhibition of return found in both experiments, but a greater amount of inhibition was found for low-frequency words than for high-frequency words. These findings suggest that inhibition of return not only inhibits returning attention to previously attended locations, but can also affect the processing that is required for lexical access.     

Listening comprehension and working memory are impaired in attention-deficit hyperactivity disorder irrespective of language impairment

This study investigated listening comprehension and working memory abilities in children with attention-deficit hyperactivity disorder (ADHD), presenting with and without language impairments (LI). A 4-group design classified a community sample (n = 77) of boys aged 9–12 into ADHD, ADHD + LI, LI, and Normal groups. Children completed tests of basic language and cognitive skills, verbal and spatial working memory, and passage-level listening comprehension. Multivariate analyses and post hoc comparisons indicated that ADHD children who did not have co-occurring LI comprehended factual information from spoken passages as well as normal children, but were poorer at comprehending inferences and monitoring comprehension of instructions. ADHD children did not differ from normal children in verbal span, but showed significantly poorer verbal working memory, spatial span, and spatial working memory. The ADHD + LI and LI groups were most impaired in listening comprehension and working memory performance, but did not differ from each other. Listening comprehension skills were significantly correlated with both verbal and spatial working memory, and parent–teacher ratings of inattention and hyperactivity/impulsivity. Findings that children with ADHD but no LI showed subtle higher-level listening comprehension deficits have implications for both current diagnostic practices and conceptualizations of ADHD.     

Semantic Compositionality and Truth-Conditional Content

It is widely held that hearers grasp an utterance's truth conditions by assigning contents to the linguistic expressions used, and combining these contents according to semantic composition rules. To preserve compositionality of truth-conditional content while accounting for context-sensitivity that is not traceable to overt linguistic form, semanticists posit covert linguistic structure. The strongest justification for this approach is the allegedly unconstrained nature of the alternative, whereby a process of 'free pragmatic enrichment' supplies constituents of content that are not traceable to (overt or covert) encoded meaning. This paper argues that free enrichment is tightly constrained by purely pragmatic factors, thus undermining the motivation for semantic compositionality.     

A randomised controlled trial of the effectiveness of writing as a self-help intervention for traumatic injury patients at risk of developing post-traumatic stress disorder

The study investigated the effects of writing and self-help information on severity of psychological symptoms in traumatic injury patients at risk for developing post-traumatic stress disorder (PTSD). Patients attending Accident and Emergency (A & E), were screened for Acute Stress Disorder and randomised to an information control group (n = 36) or a writing and information group (n = 31). Participants in both groups received an information booklet one-month post-injury. Participants in the writing group also wrote about emotional aspects of their trauma during three 20-min sessions, five to six weeks post-injury. Psychological assessments were completed within one month and at three and six months post-injury. There were significant improvements on measures of anxiety, depression and PTSD over time. Differences between groups on these measures were not statistically significant. However, subjective ratings of the usefulness of writing were high. In conclusion, the results do not currently support the use of writing as a targeted early intervention technique for traumatic injury patients at risk of developing PTSD.     

Regendering the U.S. Abortion Debate

This paper originated in a conference presentation with my colleague Michael Tooley, at which we were both asked to re-evaluate articles about abortion that each of us had written over twenty years earlier. While Tooley and I both contended that abortion should be legally unrestricted, there were striking differences in the style and content of our respective arguments. Contemplating these differences has reinforced my own belief in the importance of emphasizing the centrality of gender when discussing abortion. Since gender as we know it is a system of dominance as well as difference (MacKinnon 1987), I take this to mean that contemporary discussions of abortion must address the relationship between abortion access and the social status of women. My early article addressed this relationship to some extent, but the present paper will raise a number of additional gender issues that the early article did not mention.     

Natality and mortality: rethinking death with Cavarero

In this article I rethink death and mortality on the basis of birth and natality, drawing on the work of the Italian feminist philosopher Adriana Cavarero. She understands birth to be the corporeal event whereby a unique person emerges from the mother’s body into the common world. On this basis Cavarero reconceives death as consisting in bodily dissolution and re-integration into cosmic life. This impersonal conception of death coheres badly with her view that birth is never exclusively material but always has ontological significance as the appearance of someone new and singular in the world of relations with others. This view of birth calls for a relational conception of death, which I develop in this article. On this conception, death is always collective, affecting all those with whom the one who dies has maintained relations: As such, our different deaths shade into one another. Moreover, because each person is unique in virtue of consisting of a unique web of relations with others, death always happens to persons as webs of relations. Death is relational in this way as a corporeal, and specifically biological, phenomenon, to which we are subject as bodily beings and as interdependent living organisms. I explore this with reference to Simone de Beauvoir’s memoir of her mother’s death from cancer. Finally I argue that, on this relational conception, death is something to be feared.     

The relationship between anxiety sensitivity and latent symptoms of emotional problems: A structural equation modeling approach

A large body of research suggests that common and specific psychopathology dimensions underlie the symptoms that occur within mood and anxiety disorders. As of yet, it is unclear precisely how the facets of Anxiety Sensitivity (AS), or fear of the symptoms of fear and anxiety, relate to these latent factors. Using data from 606 adolescents participating in the baseline phase of a longitudinal study on risk factors for emotional disorders, we modeled the facets of AS as measured by the Anxiety Sensitivity Index-Expanded Form (ASI-X) and related these facets to a hierarchical model of latent symptoms of psychological distress. Results suggest that one facet of AS is associated with a broad General Distress factor underlying symptoms of most emotional disorders while others relate to intermediate-level and conceptually-meaningful narrow factors representing aspects of psychological distress specific to particular emotional disorders.     

Cross-Field Differences in Creative Problem-Solving Skills: A Comparison of Health, Biological, and Social Sciences

In the present study, 258 doctoral students working in the health, biological, and social sciences were asked to solve a series of field-relevant problems calling for creative thought. Proposed solutions to these problems were scored with respect to critical creative thinking skills such as problem definition, conceptual combination, and idea generation. Results indicated that health, biological, and social scientists differed with respect to their skill in executing various operations, or processes, involved in creative thought. Interestingly, no differences were observed as a function of the students' level of experience. The implications of these findings for understanding cross-field, and cross-experience level, differences in creative thought are discussed.     

Resources versus respect: Social judgments based on targets' power and status positions

In two experiments, we investigate how individuals' levels of power and status interact to determine how they are perceived by others. We find that power and status have similar, positive, effects on judged dominance. We also find that power has a negative effect on perceived warmth, but status moderates this “power penalty”: high power without status is associated with low warmth, but power with status is judged warm. Consequently, we find high status individuals, regardless of power level, are perceived positively - dominant and warm - whereas high power-low status individuals are judged most negatively — dominant and cold (Experiments 1 and 2). As a result, perceivers expect positive interactions with high status individuals, but negative interactions with high power, low status individuals (Experiment 2). These findings provide insight into power and status social judgments, and further our understanding of similarities and differences between these distinct, yet related, constructs.     

The impact of parents’ mental health on parent–baby interaction: A prospective study

The aims of the current study were to examine the effect of fathers’ and mothers’ pre and postnatal mental health on mother–infant and father–infant interactions. Mental health was broadly defined to include anxiety, depression and PTSD. A community sample of 44 mothers and 40 fathers from 45 families completed questionnaire measures of mental health in late pregnancy and three months postpartum. Mother–infant and father–infant interactions were observed and videoed three months postpartum and analysed using the CARE-index. Results showed that prenatal mental health, in particular anxiety, was associated with parent–infant interactions to a greater extent than postnatal mental health. Fathers’ prenatal symptoms were associated with higher paternal unresponsiveness and infant passivity whilst fathers’ postnatal symptoms were associated with higher levels of infant difficulty in the father–baby interaction. The results also indicated that mothers and fathers interaction with their babies were similar, both on average and within the couples, with 34% being inept or at risk. These findings highlight the need for early detection and prevention of both mental health and parent–infant relationship problems in fathers as well as mothers. However, further prospective and longitudinal studies are needed to understand the influences of parental mental health on the parent–infant interactions further. Also it should be noted that the mental health scores were low in this sample, which may reflect the sample characteristics. Future studies therefore would benefit from focusing on more vulnerable groups of parents.
