    Automatic and controlled processes in behavioural control: Implications for personality psychology

    Abstract This paper highlights a number of unresolved theoretical issues that, it is argued, continue to impede the construction of a viable model of behavioural control in personality psychology. It is contended that, in order to integrate motivation, emotion, cognition and conscious experience within a coherent framework, two major issues need to be recognised: (a) the relationship between automatic (reflexive) and controlled (reflective) processing and (b) the lateness of controlled processing (including the generation of conscious awareness)-phenomenally, such processing seems to 'control' behaviour, but experimentally it can be shown to postdate the behaviour it represents. The implications of these two major issues are outlined, centred on the need to integrate theoretical perspectives within personality psychology, as well as the greater unification of personality psychology with general psychology. A model of behavioural control is sketched, formulated around the concept of the behavioural inhibition system (BIS), which accounts for: (a) why certain stimuli are extracted for controlled processing (i.e. those that are not 'going to plan', as detected by an error mechanism) and (b) the function of controlled processing (including conscious awareness) in terms of adjusting the cybernetic weights of automatic processes (which are always in control of immediate behaviour) which, then, influence future automatically controlled behaviour. The relevance of this model is illustrated in relation to a number of topics in personality psychology, as well related issues of free-will and difficult-to-control behaviours

    A facial expression for anxiety.

    Anxiety and fear are often confounded in discussions of human emotions. However, studies of rodent defensive reactions under naturalistic conditions suggest anxiety is functionally distinct from fear. Unambiguous threats, such as predators, elicit flight from rodents (if an escape-route is available), whereas ambiguous threats (e.g., the odor of a predator) elicit risk assessment behavior, which is associated with anxiety as it is preferentially modulated by anti-anxiety drugs. However, without human evidence, it would be premature to assume that rodent-based psychological models are valid for humans. We tested the human validity of the risk assessment explanation for anxiety by presenting 8 volunteers with emotive scenarios and asking them to pose facial expressions. Photographs and videos of these expressions were shown to 40 participants who matched them to the scenarios and labeled each expression. Scenarios describing ambiguous threats were preferentially matched to the facial expression posed in response to the same scenario type. This expression consisted of two plausible environmental-scanning behaviors (eye darts and head swivels) and was labeled as anxiety, not fear. The facial expression elicited by unambiguous threat scenarios was labeled as fear. The emotion labels generated were then presented to another 18 participants who matched them back to photographs of the facial expressions. This back-matching of labels to faces also linked anxiety to the environmental-scanning face rather than fear face. Results therefore suggest that anxiety produces a distinct facial expression and that it has adaptive value in situations that are ambiguously threatening, supporting a functional, risk-assessing explanation for human anxiet

    Individual differences in emotion elicitation in university examinations: A quasi-experimental study

    a b s t r a c t In a quasi-experimental study, we examined the role of individual differences in the elicitation of emotional states in university examinations. Specifically, we assessed emotional states (a) before the first examination (baseline), (b) after receiving positive or negative feedback, and (c) then, again, before a series of subsequent examinations. We also measured effort in examination preparation and interest for studying. Data were collected during a university course that consisted of seven examinations in one semester; and 94 female students completed the BIS/BAS scales and SPSRQ (to measure sensitivity to punishment, SP, and reward, SR). Results revealed that higher BAS, but not SR, individuals experienced higher positive affect (PA) following positive feedback and they also showed higher levels of interest in studying. More generally, higher BIS and SP individuals experienced higher level of negative affect (NA) and they invested more effort in examination preparation; and both higher levels of SP and SR correlated positively with NA after receiving negative feedback. In addition, following negative feedback, higher BAS individuals experienced lower levels of PA, and higher SR individuals invested less effort in examination preparation. Results are discussed in terms of the reinforcement sensitivity theory (RST) of personality and directions for future research

    Avanzando con el SAC: Hacia la neurobiología del modelo multidimensional de la motivación de acercamiento

    One of the hottest topics in neuroscience is the study of brain-behavioural circuits underlying the processing of reward-related stimuli. A growing body of studies has shed new light on the neural structure of this reward system. In this paper, we discuss the significance of these studies from the perspective of a neuropsychological theory of personality, namely the Reinforcement Sensitivity Theory (RST). RST assumes that variation in sensitivity/reactivity of the reward system is the cause of individual differences in approach motivation (e.g. desire or need for achievement, persistence, and positive emotionality). Within RST, these individual differences are contained in the construct of the Behavioural Approach System (BAS). However, there is an ongoing debate as regards the nature of the BAS. This fact motivated us to review the latest refinements in the neuroscience of the BAS in the context of the reward system. In this review, we identity four distinctive aspects of the BAS: wanting, incentive motivation, striving and liking. Their behavioural effects are compared with the behavioural manifestations of testosterone, dopamine, serotonin and endogenous opioids, respectively. We conclude that the unidimensional view of the BAS is overly oversimplified; and we suggest that it should be studied as a multidimensional construct and, by implication, so too should the reward system.Uno de los temas candentes en la neurociencia es es el estudio de circuitos cerebro-conductuales que están en la base del procesamiento de estímulos relacionados con la recompensa. El número creciente de investigaciones han arrojado una nueva luz sobre la estructura neuronal de este sistema de recompensas. En este trabajo discutimos la importancia estos estudios desde la perspectiva de la teoría neuropsicológica de la personalidad, más concreto, la Teoría de la Sensibilidad al Refuerzo (TSR). TSR supone que la variación en la sensibilidad/reactividad del sistema de recompensas es la causa de diferencias individuales en la motivación de acercamiento (p. ej. deseo o necesidad de logro, perseverancia y emocionalidad positiva). Dentro de TSR estas diferencias individuales se encuentran en el constructo del Sistema de activación conductual (SAC). Sin embargo, existe un debate sobre la índole de SAC. Este hecho nos ha motivado a revisar los últimos hallazgos en la neurociencia de SAC en el contexto del sistema de recompensas. En esta revisión identificamos cuatro aspectos distintivos de SAC: carencia, motivación de incentivo, esfuerzos y gustos. Sus efectos conductuales se comparan con las manifestaciones de testosteronas, dopamina, serotonina y opioides endógenos, respectivamente. Concluimos que la vista unidimensional de SAC es demasiado simplificada y sugerimos estudiarlo como un constructo multidimensional, lo que implica lo mismo para el sistema de recompensas

    Perfectionism and personality

    This chapter provides a synopsis of research on where multidimensional perfectionism “fits” within the broader framework of contemporary personality theory. Focusing on Hewitt and Flett’s (1991) model of perfectionism--differentiating self-oriented, other-oriented, and socially prescribed perfectionism--the chapter presents a summary and critical discussion of how multidimensional perfectionism relates to the dimensions and facets of two major structural models of personality (the five-factor model and the HEXACO model) and one neuropsychological model of personality (reinforcement sensitivity theory). Implications of the findings for multidimensional theories and models of perfectionism, as well as future perfectionism research, are discussed
