An exploration of cognitive appraisals following spinal cord injury

This study explored the cognitive appraisals that people make following spinal cord injury (SCI) about their situation and their ability to cope with it. Appraisals are thought to be important in determining individual responses to different events and have been shown to predict psychological well-being following injury. A cross-sectional interview study was used. Ten individuals who had recently started rehabilitation at the National Spinal Injuries Centre following an SCI were interviewed. Eight men and two women with a variety of injury level and completeness participated. Interviews were semi-structured and aimed to elicit participants' appraisals of their experiences and their ability to cope. Interviews were analysed qualitatively using interpretative phenomenological analysis. Four super-ordinate themes emerged from the interviews. These were making sense of a traumatic experience, impact of the SCI, coping and altered view of self and life. The interviews revealed that appraisals following SCI are complex and relate not only to the individual but also to their context, life stage, roles and relationships. The study adds to the theoretical understanding of the appraisal process following SCI. Ideas for further research are generated and clinical implications for improving patient experiences and developing appraisal-focused interventions are considered.     

Theoretical perspectives on eye movements in reading: Past controversies,current issues,and an agenda for future research

The study of eye movements has become a well established and widely used methodology in experimental reading research. This Introduction provides a survey of some key methodological issues, followed by a discussion of major trends in the development of theories and models of eye movement control in fluent reading. Among the issues to be considered in future research are problems of methodology, a stronger grounding in basic research, integration with the neighbouring area of research on single word recognition, more systematic approaches to model evaluation and comparison, and more work on individual variation and effects of task demands in reading.     

How do shoppers behave online? An observational study of online grocery shopping

The pace of online shopping revenue growth means it is important for retailers and manufacturers to understand how consumers behave online compared with their behaviour in brick and mortar stores. We conducted a study in which the detailed behaviour of 40 shoppers was screen recorded while they each undertook an online shopping ‘trip’. The shopping trip comprised purchasing a basket of 12 commonly bought grocery categories at one of two major retailers. The shoppers were all inexperienced in online grocery shopping. Results show that online grocery shopping is fast, even for these consumers who were new to it – half of the online shoppers spent less than 10 seconds purchasing from a category. This result is very similar to that of past studies in physical stores. Indeed, half of all the 12 item‐shopping trips took less than 10 minutes. Also, most purchases were made from the first category page displayed in the retailer's online store. Shoppers also consistently used the default display options chosen by the retailers but used a combination of navigational tools to find their products. We conclude that online shoppers do not behave differently from those offline in terms of time spent or effort expended. Online shopping, in the grocery context at least, seems to primarily reflect a desire for time efficiency on the part of the shopper. In that regard, online shopping seems very similar to in‐store shopping. The study begins the job of documenting shopper behaviour into this new channel and provides practical knowledge for retailers and manufacturers. Copyright © 2015 John Wiley & Sons, Ltd.     

General Education Participation Improves the Social Contacts and Friendship Networks of Students with Severe Disabilities

One desired outcome of inclusive education is the enhanced social development of students with disabilities. Some have suggested that planned and systematic support of students with severe disabilities in general education environments may lead to greater social interaction between these students and their peers without disabilities. In an effort to analyze this proposition, we studied two students with severe disabilities as they began participating in general education classrooms. Using within-student multiple baseline designs across class periods, the effects of participating in general education were studied across a range of social participation indicator variables. Our results suggest that planned and systematic efforts to include students with severe disabilities into general education courses can have positive effects on their social contacts and friendship networks. Our findings are discussed in relation to policy efforts to establish inclusive education in public schools, strategies for structuring general education participation, and the potential effects such efforts can have on the social inclusion of students with disabilities.     

Perceptual, not memorial, disruption underlies emotion-induced blindness

Emotion-induced blindness refers to impaired awareness of stimuli appearing in the temporal wake of an emotionally arousing stimulus (S. B. Most, Chun, Widders, & Zald, 2005). In previous emotion-induced blindness experiments, participants withheld target responses until the end of a rapid stream of stimuli, even though each target appeared in the middle of the stream. The resulting interval between the targets' offset and participants' initiation of a response leaves open the possibility that emotion-induced blindness reflects a failure to encode or maintain target information in memory rather than a failure of perception. In the present study, participants engaged in a typical emotion-induced blindness task but initiated a response immediately upon seeing each target. Emotion-induced blindness was nevertheless robust. This suggests that emotion-induced blindness is not attributable to the delay between awareness of a target and the initiation of a response, but rather reflects the disruptive impact of emotional distractors on mechanisms driving conscious perception.     

Neuroreceptor imaging of stress and mood disorders

Techniques such as positron emission tomography and single photon emission computed tomography allow for the imaging of neurotransmitter receptors and transporters in the brain. These tools have been used to investigate serotonergic, dopaminergic, and opioidergic function in healthy subjects as well as in patients with major depressive disorder, bipolar disorder, and other mood disorders. Pharmacologic challenges, such as amphetamine challenge, and physiologic stressors, such as pain challenge, have been used to further examine the function of these neurotransmitter systems. Neuroimaging of patient populations before and after medication treatment may be useful to understand changes in neurotransmission that accompany disease remission. As new radiotracers with higher selectivity for the various receptors and transporters are developed, imaging techniques may provide new insights into the pathophysiology of mood disorders, leading to improved diagnosis and treatment.     

A behavior-analytic conceptualization of the side effects of psychotropic medication

A range of behavior-much deemed problematic by society-is treated with behavioral methods or psychotropic medications. Although the processes associated with behavioral interventions have been investigated using conceptual, experimental, and applied analyses, less is known about the behavioral processes associated with the use of psychotropic medication. Psychotropic drugs produce at least two types of effects of behavioral interest: (a) primary effects of drug action on target behaviors and (b) side effects that change the target or other behavior. Although an empirical literature exists regarding the former effects, little attention has been given to the latter topic. In this paper we offer a conceptual analysis of the side effects of psychotropic medication. We propose that the side effects of various drugs can influence behavior by functioning as motivating operations, conditional or discriminative stimuli, or by establishing new response-reinforcer relations. This conceptualization may facilitate the empirical analysis of how psychotropic drugs change behavior.     

Hyperlexia profiles

Two hyperlexic individuals were tested on reading outcome measures and on basic skills shown to be critical in reading acquisition. Results suggested distinct pathways to superior word recognition skills that can be described under a contemporary model of skilled reading, with differential acquisition of basic skills; superior word recognition skill was associated in both cases with specialized development in one basic area, that of orthographic processing. Results supported an asset rather than a deficit analysis of hyperlexia: Rather than assimilating to reading pathology (dyslexia) subtypes, hyperlexia was seen to be accompanied by assets that are absent in dyslexic profiles.     

Which way is upright and normal? Haptic perception of letters above head level.

In three experiments, the perception of the apparent orientation of block letters shown in various orientations above the subject's head in the horizontal plane was examined. A block letter F with its front facing down toward the observer has two crossbars on its right side; the top is the part with the long crossbar, and the base has no bar. The experiments involved changing the locations of these parts with respect to the observer. In Experiment 1, the subjects using touch most often identified a letter as having its left and right sides in a normal orientation if the front of the block letter faced upwards away from the observer, with the bar on the right and the top of the letter farther from the subject than the letter's base. In Experiment 2, the subjects judging visual uprightness favored positions in which the bars were on the right, the top of the block letter was near them, and the letter's front faced downwards toward the observer. In Experiment 3, the subjects using touch most often assessed letters as being upright if the top of the letter was the farthest part and the bar was on the right. The results suggest that, when assessing orientation, subjects using touch favored positions that would be reached by a letter moving vertically upwards from table height, but subjects relying on vision favored positions reached by a letter moving in an are centered on the subject's head (on the eyes, in particular).     

Replicating the five factor model of personality in a psychiatric sample

In this study we examined whether the factor structure and traits of the five-factor model of personality (FFM), derived from non-clinical samples, could be replicated in a sample of psychiatric patients. The revised NEO Personality Inventory (NEO PI-R) was administered to a study group of psychiatric patients (n=176). The test scores from these patients were intercorrelated, factor analyzed and the obtained factor structure was then compared to the factor structure of the normative data from the NEO PI-R. The factor structure from the psychiatric study group and that from the normative sample were virtually identical, with all five factors showing significant congruence. These results argue favorably for the clinical applicability of the FFM with psychiatric patients.
