The recognition of reduced word forms

This article addresses the recognition of reduced word forms, which are frequent in casual speech. We describe two experiments on Dutch showing that listeners only recognize highly reduced forms well when these forms are presented in their full context and that the probability that a listener recognizes a word form in limited context is strongly correlated with the degree of reduction of the form. Moreover, we show that the effect of degree of reduction can only partly be interpreted as the effect of the intelligibility of the acoustic signal, which is negatively correlated with degree of reduction. We discuss the consequences of our findings for models of spoken word recognition and especially for the role that storage plays in these models.     

"Markov at the bat": a model of cognitive processing in baseball batters

Anecdotal evidence from players and coaches indicates that cognitive processing (e.g., expectations about the upcoming pitch) plays an important role in successful baseball batting, yet this aspect of hitting has not been investigated in detail. The present study provides experimental evidence that prior expectations significantly influence the timing of a baseball swing. A two–state Markov model was used to predict the effects of pitch sequence and pitch count on batting performance. The model is a hitting strategy of switching between expectancy states using a simple set of transition rules. In a simulated batting experiment, the model provided a good fit to the hitting performance of 6 experienced college baseball players, and the estimated model parameters were highly correlated with playing level.     

Tool-use and the left hemisphere: What is lost in ideomotor apraxia?

Impaired tool related action in ideomotor apraxia is normally ascribed to loss of sensorimotor memories for habitual actions (engrams), but this account has not been tested against a hypothesis of a general deficit in representation of hand-object spatial relationships. Rapid reaching for familiar tools was compared with reaching for abstract objects in apraxic patients (N = 9) and in a control group with right hemisphere posterior stroke. The apraxic patients alone showed an impairment in rotating the wrist to correctly grasp an inverted tool but not when inverting the hand to avoid a barrier and grasp an abstract object, and the severity of the impairment in tool reaching correlated with pantomime of tool-use. A second experiment with two apraxic patients tested whether barrier avoidance was simply less spatially demanding than reaching for a tool. However, the patient with damage limited to the inferior parietal lobe still showed a selective problem for tools. These results demonstrate that some apraxic patients are selectively impaired in their interaction with familiar tools, and this cannot be explained by the demands of the task on postural or spatial representation. However, traditional engram theory cannot account for associated problems with imitation of novel actions nor the absence of any correlated deficit in recognition of the methods of grasp of common tools. A revised theory is presented which follows the dorsal and ventral streams model ( Milner & Goodale, 2008) and proposes preservation of motor control by the dorsal stream but impaired modulating input to it from the conceptual systems of the left temporal lobe.     

Bernstein's Theory of Movement Behavior: Historical Development and Contemporary Relevance

The traditional concept of cerebral dominance relies for support on the facts of handedness and the association of propositional speech with the leading hemisphere. This is regarded as evidence for specialization but not that the hemispheres are involved in an unchanging dominance relationship. The fact that the corpus callosum forms a bridge between the hemispheres means that they are not isolated units and that one may work through the other to control the functions of the limbs. Control however may be switched as the tasks demand the respective specializations of each hemisphere.     

Managing Retirement—Rethinking Links between Individual and Organization

Retirement represents an important life event in Western countries marking the transition from one life stage to another and the movement from being within to being outside the labour force. For employees, retirement might represent the border between organizational life and life outside the workplace. This border, though commonly thought of as fixed and distinct, is becoming more and more blurred. Organizations and organizational psychology have thus far largely ignored retirement as a relevant topic. However, the changing nature of retirement, as a consequence of demographic changes and developments in the labour market, means that we need to rethink our assumptions about retirement and to attempt to specify some of the missing links between individual and organizational perspectives on retirement. We will argue that retirement is not only an important event in the life of working individuals but has become an important issue for management. This article will discuss some individual retirement processes and possible impacts of retirement on the organization focusing, in particular, on the use of early retirement schemes as a management tool replacing traditional redundancies. It is suggested that these early retirement schemes neglect some basic aspects of individual and organizational retirement processes and are likely therefore in some cases to be less than effective. By describing a different model for managing retirement we aim to suggest how a better balance between individual and organizational needs can be achieved.     

Cultural and learning differences in the Judd illusion

In the present study, we examined whether individual differences in the perception of illusory Judd drawings point to variability in the pickup of informational variables. Two sources for these individual differences were addressed: culture and learning. East Asian (n = 24) and Western (n = 24) participants made perceptual judgments of the midpoint of the shaft of various Judd figures in a pretest–practice–posttest design. During practice, half of the participants received feedback about the actual midpoint after each trial, while the other half did not receive feedback. The results showed differences among perceivers of different cultures in judging the midpoints of the shafts of Judd figures, particularly with respect to their propensity to improve perceptual accuracy after repeated practice and feedback. For most participants, changes in illusory bias as a consequence of learning were shown to reflect either a change in what informational variable they exploited or a rescaling or calibration of the perception to the informational variable. However, the individual differences in illusory bias related to culture could not be unequivocally attributed to either of these perceptual-learning processes.     

The illness perception questionnaire: A new method for assessing the cognitive representation of illness

Abstract

The Illness Perception Questionnaire (IPQ) is a new method for assessing cognitive representations of illness. The IPQ is a theoretically derived measure comprising five scales that provides information about the five components that have been found to underlie the cognitive representation of illness. The five scales assess identity - the symptoms the patient associates with the illness, cause - personal ideas about aetiology, time-line - the perceived duration of the illness, consequences - expected effects and outcome and cure control - how one controls or recovers from the illness. The IPQ has a specific number of core items but allows the user to add items for particular patient groups or health threats. Data is presented supporting the reliability and validity of the IPQ scales in different chronic illness populations.     

Humour in advertising: An associative processing model

This chapter reviews a research programme on the effects of humour in advertising on positive and negative brand associations and brand choice, and integrates the findings into a single overarching model. Based on the Associative and Propositional Processes Model of Evaluation (Gawronski & Bodenhausen, 2006, 2007, 2011), we propose that repeated pairings of a novel brand with brand-unrelated humour forms positive brand associations, which mediate spontaneous brand choice. This associative process was found to be independent from the level of distraction posed by humour and from awareness of the stimulus pairings. In fact the distraction posed by humour benefits persuasion by preventing negative brand associations. Previous marketing research, which mainly viewed humour as a cue in peripheral processing, was rather pessimistic about the persuasive impact of humour. In contrast, this research programme suggests that a repeated pairing of a brand with humour affects the brand’s underlying associative structure, which may lead to stable attitude changes that guide overt spontaneous brand choice. Theoretical and practical implications are discussed.
