Cross-modal information integration in category learning

An influential theoretical perspective describes an implicit category-learning system that associates regions of perceptual space with response outputs by integrating information preattentionally and predecisionally across multiple stimulus dimensions. In this study, we tested whether this kind of implicit, information-integration category learning is possible across stimulus dimensions lying in different sensory modalities. Humans learned categories composed of conjoint visual–auditory category exemplars comprising a visual component (rectangles varying in the density of contained lit pixels) and an auditory component (in Exp. 1, auditory sequences varying in duration; in Exp. 2, pure tones varying in pitch). The categories had either a one-dimensional, rule-based solution or a two-dimensional, information-integration solution. Humans could solve the information-integration category tasks by integrating information across two stimulus modalities. The results demonstrated an important cross-modal form of sensory integration in the service of category learning, and they advance the field’s knowledge about the sensory organization of systems for categorization.     

British-English norms and naming times for a set of 539 pictures: The role of age of acquisition

In the present study, we presented picture-naming latencies along with ratings for a set of important characteristics of pictures and picture names: age of acquisition, frequency, picture-name agreement, name agreement, visual complexity, familiarity, and word length. The validity of these data was established by calculating correlations with previous studies. Regression analyses show that our ratings account for a larger amount of variance in RTs than do previous data. RTs were predicted by all variables except complexity and length. A complete database presenting details about all of these variables is available in the supplemental materials, downloadable from http://brm.psychonomic-journals.org/content/supplemental.     

A naturalistic study of the effectiveness of time-limited counselling with low-income clients

The role of counselling and psychotherapy services in relation to the needs of economically disadvantaged individuals has been largely neglected in the recent research literature. Although a small number of theoretical papers and case analyses have been published, there is an absence of studies that examine the effectiveness of counselling with this client group. The present paper reports on a naturalistic outcome study of the effectiveness of time-limited counselling (seven sessions) with low-income clients. Analysis of pre-counselling, postcounselling and follow-up measures of mental health and problem ratings indicated levels of change equivalent to those achieved in controlled studies of counselling and psychotherapy with other client groups. Factors influencing the effectiveness of counselling included gender and employment status. Qualitative client reports suggested that the main benefits experienced by clients were in the areas of self-understanding and self-belief. For illustrative purposes, data from low-income clients are compared with results from employee counselling clients receiving a similar service. The implications of these findings for further research are discussed.     

Repetition priming of access to biographical information from faces

Two experiments examined repetition priming on tasks that require access to semantic (or biographical) information from faces. In the second stage of each experiment, participants made either a nationality or an occupation decision to faces of celebrities, and, in the first stage, they made either the same or a different decision to faces (in Experiment 1) or the same or a different decision to printed names (in Experiment 2). All combinations of priming and test tasks produced clear repetition effects, which occurred irrespective of whether the decisions made were positive or negative. Same-domain (face-to-face) repetition priming was larger than cross-domain (name-to-face) priming, and priming was larger when the two tasks were the same. It is discussed how these findings are more readily accommodated by the Burton, Bruce, and Johnston () model of face recognition than by episode-based accounts of repetition priming.     

Freedom from and Freedom for: Luther's Concept of Freedom for the Twenty‐First Century

This article examines Martin Luther's two fundamental claims around Christian freedom. Drawing on Luther, I suggest three primary characteristics of Christian freedom that should be recovered and championed in our twenty‐first‐century context: it is relational, it is a gift; and it contains within it an ethical imperative for the sake of the neighbor. Together, these three characteristics point to the fact that in a Christian understanding, “freedom” is never considered by itself, but only in the larger context of “freedom from” and “freedom for.”     

Leader Behavior,Work-Attitudes,and Turnover of Salespeople: An Integrative Study

Data were collected from the national field sales force of a major consumer goods manufacturer. The study develops a structural model of salespeople's perceptions of their supervisors' behaviors (i.e., leadership consideration and leadership role clarity), and the influence of supervisors' behaviors on the sales force's role perceptions, job anxiety, job satisfaction, propensities to leave and actual turnover. The study integrates previous research regarding sales force turnover to form the underpinning for the relationships between the constructs, and finds empirically that sales managers' leadership behaviors directly and indirectly influence job satisfaction, which influences salespeople's propensity to leave the organization and actual turnover.     

Current issues and new directions in psychology and health : What happened to behaviour in the decade of behaviour?

This editorial addresses two key aspects of the investigation of behaviour: the science and the application. On the one hand, researchers and policy makers recognise a need for good scientific evidence about behaviour and behaviour change, but are slow to turn to psychology for such evidence. On the other hand, there is a gap in scientific thinking about behaviour and behaviour change.     

“Test-Tube Baby” procedures: Stress and judgements under uncertainty

Patients participating in an in vim fertilisation with embryo transfer (IVF and ET) programme face uncertainty at each stage of the procedure. Research on heuristics and on stress lead to predictions about behaviour in situations of uncertainty. It was predicted that IVF and ET participants would overestimate the likelihood of success, due to publicity the process has received, and would underestimate the likelihood of an earlier, less publicised. stage in the procedure. Both predictions were confirmed in a total of 70 participants (26 women at out-patient clines, 23 of their partners and 21 surgical in-patients). All the men and all but one woman overestimated the likelihood of becoming pregnant and having a baby. and most of the surgical patients underestimated the likelihood of egg recovery. Estimates were not related to patients' confidence about their information, confirming previous evidence about confidence in inaccurate judgements based on heuristics. Data on patients' distress as indicated by mood rating show high anxiety at points of uncertainty and Pailure, as found in other studies of stress. While the couples shared their inaccurate judgements. they did not necessarily share their distress. The results are discussed in terms of patients' decision making. coping strategies and the implications for doctor-patient communication.     

Applying multiple models to predict clinicians’ behavioural intention and objective behaviour when managing children's teeth

This study used multiple theoretical approaches simultaneously to predict an objectively measured clinical behaviour. The six theoretical approaches were: The Theory of Planned Behaviour (TPB), Social Cognitive Theory (SCT), Common Sense Self-Regulation Model (CS-SRM), Operant Learning Theory (OLT), Action Planning (AP) and the Precaution Adoption Process (PAP), with knowledge as an additional predictor. Data on variables from these models were collected by postal survey. Data on the outcome behaviour, the evidence-based practice of placing fissure sealants, was collected from clinical records. Participants were 133 dentists (64% male) in Scotland. Variables found to predict the behaviour were: intention, attitude, perceived behavioural control, risk perception, outcome expectancies, self efficacy, habit, anticipated consequences, experienced consequences and action planning. The TPB, SCT, AP, OLT and PAP significantly predicted behaviour but the CS-SRM did not. A combined (Stepwise) regression model included only intention and action planning. Post hoc analyses showed action planning mediated effect of intention on behaviour. Taking a theory-based approach creates a replicable methodology for identifying factors predictive of clinical behaviour and for the design and choice of interventions to modify practice as new evidence emerges, increasing current options for improving health outcomes through influencing the implementation of best practice.
