Units of visual individuation in rhesus macaques: objects or unbound features?

Vision begins with the processing of unbound visual features, which must eventually be bound together into object representations. Such feature binding is required for coherent visual perception, and accordingly has received a considerable amount of study in several domains. Neurophysiological work, often in monkeys, has revealed the details of how and where feature binding occurs in the brain, but methodological limitations have not allowed this research to elucidate just how feature binding operates spontaneously in real-world situations. In contrast, behavioral work with human infants has demonstrated how we use simpler unbound features to individuate and identify objects over time and occlusion in many types of events, but this work has not typically been able to isolate the role of feature binding in such processing. Here we provide a method for assessing the spontaneity and fidelity of feature binding in non-human primates, as this process is utilized in real-world situations, including simple foraging behaviors. Using both looking-time and manual-search measures in a natural environment, we show that free-ranging rhesus macaques (Macaca mulatta) spontaneously bind features in order to individuate objects across time and occlusion in dynamic events. This pattern of results demonstrates that feature binding is used in subtle ways to guide ecologically relevant behavior in a non-human animal, spontaneously and reliably, in its natural environment.     

Intervenciones familiares en el tratamiento de los pacientes con esquizofrenia: aproximaciones recientes

Resumen

Después de mencionar los postulados básicos que subyacen a los modelos tradicionales de terapia familiar a los que se han planteado serias críticas, se revisan nuevos modelos que superan estas limitaciones. Estos nuevos modelos de intervención familiar comparten dos características principales: considerar a los familiares aliados naturales del proceso de rehabilitación del paciente y basarse en el empleo de estrategias terapéuticas claramente operacionalizadas. Se describen brevemente cuatro de estas estrategias y se revisa la evidencia que apoya su eficacia: la terapia familiar orientada a la crisis de Goldstein, el paquete de intervenciones psicosociales desarrollado por Leff y cols., la terapia familiar conductual de Falloom y el programa de psicoeducación familiar de Anderson y cols. Su eficacia es analizada en términos de la disminución observada en las tasas de recaídas y en la consecución de otros beneficios para el paciente y la familia. Se señalan un conjunto de principios generales que deben presidir las intervenciones con estas familias. Por último, se hace una reflexión acerca de algunas deficiencias que estudios futuros han de subsanar para poder alcanzar unas conclusiones más sólidas sobre la eficacia de estos nuevos procedimientos terapéuticos.     

Will you thrive under pressure or burn out? Linking anxiety motivation and emotional exhaustion

Can individual differences in the tendency to use anxiety as a source of motivation explain emotional exhaustion? We examined the effects of using anxiety as a source of energy or as a source of information (viewed here as two forms of anxiety motivation) on emotional exhaustion. In Study 1, the use of anxiety as a source of energy predicted decreased emotional exhaustion one year later. Moreover, both forms of anxiety motivation buffered people from the detrimental effects of trait anxiety on later emotional exhaustion. In Study 2, an experiment, participants who were instructed to use anxiety as a source of energy reported lower emotional exhaustion following a stressful task, compared to those instructed to focus on the task or to simply do their best. These findings suggest that using anxiety as a source of motivation may protect people against emotional exhaustion.     

Performance in Autobiographical Memory of Older Adults with Depression Symptoms

The aim of this study was to compare the performance in the Autobiographical Memory Test in older adults with high scores on depression symptoms (HDS) compared with a matched group with low scores on depression symptoms (LDS) according to the clinical cut‐off of the Centre for Epidemiological Studies Depression Scale. Participants were asked to generate specific autobiographical memories in response to a series of positive and negative cue words. Latencies of responses for each item were also scored. LDS participants showed a higher proportion of specific memories than HDS participants. Latencies of responses to positive and negative cues were greater for HDS than LDS. Specific autobiographical memory was positively associated with Life Satisfaction. Cognitive emotional changes in the function of memory with age are suggested as a possible explanation for the findings. Copyright © 2012 John Wiley & Sons, Ltd.     

Thought insertion: Abnormal sense of thought agency or thought endorsement?

The standard approach to the core phenomenology of thought insertion characterizes it in terms of a normal sense of thought ownership coupled with an abnormal sense of thought agency. Recently, Fernández (2010) has argued that there are crucial problems with this approach and has proposed instead that what goes wrong fundamentally in such a phenomenology is a sense of thought commitment, characterized in terms of thought endorsement. In this paper, we argue that even though Fernández raises new issues that enrich the topic, his proposal cannot rival the version of the standard approach we shall defend.     

A theoretical exploration and model of consumer expectations,post‐purchase affective states and affective behaviour

Through a detailed review of the service quality and (dis)satisfaction literatures, this paper presents a theoretical model exploring the interrelationship between expectations, affective post‐purchase states and affective behaviour. Drawing together a comprehensive hierarchy of expectations culled from the service quality literature, the authors seek to apply levels of expectation to specific post‐purchase affective states and affective behaviour. The authors argue that consumers have two types of expectation that influence post‐purchase affective states: the core or predictive ‘will be’ expectation; and peripheral expectations—that can range from the ideal standard to the minimum tolerable level. By applying the levels‐of‐expectation approach to the expectation‐disconfirmation paradigm, the authors argue that there are four types of post‐purchase affective states: delight, satisfaction (or positive indifference), acceptance (or negative indifference) and dissatisfaction. These four states may lead onto affective action—ie varying degrees of complaining or complimenting behaviour. The paper presents 11 propositions relating to expectations and their interrelationship with post‐purchase affective states and subsequent consumer behaviour, with the aim of stimulating further scholarly enquiry. The managerial implications of the analysis are also considered. Copyright © 2003 Henry Stewart Publications.     

A Transcultural Integrative Model for Ethical Decision Making in Counseling

The Transcultural Integrative Ethical Decision‐Making Model in counseling addresses the need for including cultural factors in the process of ethical dilemma resolution. This transcultural model incorporates state‐of‐the‐art concepts from multicultural theory into an ethical decision‐making model that is adapted primarily from the Integrative Model developed by V. M. Tarvydas (1998). When appropriate, this transcultural model includes aspects of other ethical resolution models, such as R. R. Cottone's (2001) Social Constructivist Model and A. H. Davis's (1997) Collaborative Model. The proposed model is presented in a step‐by‐step, linear format that can be used by counselors facing ethical dilemmas in a variety of settings and with different cultural groups.
