Response-specifying cue for action interferes with perception of feature-sharing stimuli

Perceiving a visual stimulus is more difficult when a to-be-executed action is compatible with that stimulus, which is known as blindness to response-compatible stimuli. The present study explored how the factors constituting the action event (i.e., response-specifying cue, response intention, and response feature) affect the occurrence of this blindness effect. The response-specifying cue varied along the horizontal and vertical dimensions, while the response buttons were arranged diagonally. Participants responded based on one dimension randomly determined in a trial-by-trial manner. The response intention varied along a single dimension, whereas the response location and the response-specifying cue varied within both vertical and horizontal dimensions simultaneously. Moreover, the compatibility between the visual stimulus and the response location and the compatibility between that stimulus and the response-specifying cue was separately determined. The blindness effect emerged exclusively based on the feature correspondence between the response-specifying cue of the action task and the visual target of the perceptual task. The size of this stimulus–stimulus (S–S) blindness effect did not differ significantly across conditions, showing no effect of response intention and response location. This finding emphasizes the effect of stimulus factors, rather than response factors, of the action event as a source of the blindness to response-compatible stimuli.     

The Lifecycle of Evolution: Power,Progress, and Purpose in the Advance of Civilization

This paper presents a framework for understanding that rather mysterious process by which life evolved into diverse biological species, then produced humankind, founded civilization, and is now creating high-tech societies that are entering space. A macrotechnological analysis reveals that evolution fundamentally consists of seven waves of technological innovation forming a "Life Cycle of Evolution," which is roughly comparable to the ordinary life cycles of all organisms. Finally, I note that this organic process of planetary development is drawn inexorably toward heightened awareness, existential choices, and other transcendent concerns for the same reason all phases of progress have evolved-out of sheer necessity.     

How do within-person changes due to aging affect job performance?

As the mean age of the workforce in industrialized countries trends upward, increasing attention has been paid to group-level differences between younger and older workers in terms of job performance. The present article takes an alternative perspective by examining within-person changes that occur with aging and how the process of aging affects employees' workplace behavior. We begin by highlighting five areas in which we observe major within-person changes related to aging: (1) cognitive capacity, (2) personality, (3) goal orientation, (4) social-emotional experience, and (5) health. Then, we demonstrate why and how these within-person changes due to aging affect core task performance, citizenship behavior, and counterproductive work behavior across the lifespan.     

Reflections on research and learning from the patient: the art and science of what we do

Over three decades ago, John Bowlby argued for psychoanalysis to seek beyond its own parameters if it was to maintain its claim to be a science. Since then there has been a wealth of relevant research from various fields. While this has been instrumental in the development of my own work, this paper concerns learning from the patient. The paper begins with a premise: interpretative analytic work requires three‐dimensionality (self, other and object). Although interpretative work may be ingrained in our professional identity, this triangulation may or may not exist in our patients in any stable way. The paper continues with a brief developmental account of how early archetypally‐shaped shifts in the infant's field of interest establish the experiential components of three‐dimensionality. From there, observational and clinical material with a toddler and a young boy describe how early relational deficits hindered their capacities for three‐dimensionality. Yet both were able to engage with the therapist and to become active in the creation of three‐dimensionality within their own minds. Implied in this work are considerations for working with patients for whom interpretations do not work. Michael Fordham's comments on ‘working out of the self’ are linked with the art of what we do.     

Application of the Theory of Planned Behaviour in Behaviour Change Interventions: A Systematic Review

This paper reviews studies explicitly applying the Theory of Planned Behaviour (TPB) to behaviour change interventions. A systematic and multiple search strategy identified 30 papers, describing 24 distinct interventions. Studies were rarely explicit about use of the TPB. The TPB was mainly used to measure process and outcome variables and to predict intention and behaviour, and less commonly to develop the intervention. Behaviour change methods were mostly persuasion and information, with increasing skills, goal setting, and rehearsal of skills used less often. When reported, half of the interventions were effective in changing intention, and two-thirds in changing behaviour, with generally small effect sizes, where calculable. Effectiveness was unrelated to use of the theory to develop interventions. Evidence about mediation of effects by TPB components was sparse. The TPB may have potential for developing behaviour change interventions, but more comprehensive studies are needed that compare the utility of the TPB with other social cognition models and behavioural techniques.     

Active but not consistent: dietary behaviour and the stages of change model

In Stages of Change studies on dietary fat, standard algorithms allocate many respondents to the maintenance stage and their stage allocations are not always supported by objective criteria. In defining the preparation stage standard instruments emphasise inactivity allied to confident intention to change. In contrast Lamb and Joshi's (1996) staging instrument emphasises inconsistent effort, and thereby allocates inconsistently active respondents to preparation when a standard instrument might place them in action or maintenance. In the current cross-sectional study 375 respondents completed a standard algorithm, the Lamb and Joshi instrument and a 24-hour recall food diary. They also gave judgements of their current weight and diet. Unlike the standard instrument, the Lamb and Joshi instrument: (a) allocated fewer respondents to action/maintenance, (b) discriminated key behavioural stages by percent fat in diet, and (c) captured non-linear discontinuities in the respondents’ weight and diet self-perceptions. Such discontinuities in the psychosocial processes are predicted by the transtheoretical model, and support the claim that its stages are categorically distinct rather than artificially isolated points on a continuum. Distinguishing between respondents who describe themselves as consistently active and those who describe themselves as inconsistently active may help to overcome some apparent problems in the application of the transtheoretical model to behavioural change.     

Self-injury and readiness to recover: Preliminary examination of components of the stages of change model

The purpose of this study was to examine non-suicidal self-injury (NSSI) recovery through the lens of the transtheoretical model of stages of change. To do this, a content analysis of online posts about NSSI from 73 participants (M_age = 19.4; SD_age = 5.49) with a history or NSSI was performed. Specifically, two rubrics were used. The first examined stages of change and the other positive and negative views toward NSSI recovery. Results indicated that a preponderance of posts was in the precontemplation (39.7%) and contemplation (52.1%) stages. Individuals in the contemplation stage mentioned significantly more disadvantages than advantages to change compared to those in the precontemplation stage. Overall, the current study provides preliminary evidence for the utility of stages of change when conceptualizing NSSI recovery. Implications for research and practice are addressed.     

Sustained attention can create an (illusory) experience of seeing dynamic change

Recent studies speculated that two types of change detection exist, one involving the experience of seeing dynamic change (change over brief interval), the other involving detecting a completed change (change over long interval), with only the former requiring sustained attention. To examine this supposition, a flicker change detection task was conducted in which the spatial location of objects was manipulated (shift, no-shift). In shift conditions, changed image display appeared in different locations than they did in the original display. The time interval separating images was manipulated (200 or 1000 ms). Results showed that a shift led to poor change detection only in the short interval condition. The performance decline by the image shift was not attenuated even when participants knew beforehand whether or not a shift would occur. Results indicate that sustained attention, which is sustained for a brief time, is related to the experience of seeing dynamic change.     

Spatiotemporal configuration of memory arrays as a component of VWM representations

Visual working memory (VWM) has been found to support a very limited representation of visual information and yet relatively little is known about the mechanisms that underlie this important cognitive construct. Prior investigations have revealed that VWM performance can be affected by relatively minor changes in the test method as well as the method of encoding. In the present two experiments, we separately investigated these two factors. The results suggest that sequential object displays can improve VWM performance significantly but that a lack of context relatedness between encoding and retrieval impairs performance. This impairment seems to be caused by a mismatch in the spatiotemporal configuration of the memory and test displays, and, importantly, cannot be compensated by selective attention. These findings suggest that spatiotemporal configuration information may be a fundamental component of the information that is stored in VWM as suggested by a number of influential theories.     

Dynamic binding of identity and location information: a serial model of multiple identity tracking

Tracking of multiple moving objects is commonly assumed to be carried out by a fixed-capacity parallel mechanism. The present study proposes a serial model (MOMIT) to explain performance accuracy in the maintenance of multiple moving objects with distinct identities. A serial refresh mechanism is postulated, which makes recourse to continuous attention switching, a capacity-limited episodic buffer for identity-location bindings, indexed location information stored in the visuospatial short-term memory, and an active role of long-term memory. As identity-location bindings are refreshed serially, a location error is inherent for all other targets except the focally attended one. The magnitude of this location error is a key factor in predicting tracking accuracy. MOMIT’s predictions were supported by the data of five experiments: performance accuracy decreased as a function of target set-size, speed, and familiarity. A mathematical version of MOMIT fitted nicely to the observed data with plausible parameter estimates for the binding capacity and refresh time.
