The effects of transient attention on spatial resolution and the size of the attentional cue

It has been shown that transient attention enhances spatial resolution, but is the effect of transient attention on spatial resolution modulated by the size of the attentional cue? Would a gradual increase in the size of the cue lead to a gradual decrement in spatial resolution? To test these hypotheses, we used a texture segmentation task in which performance depends on spatial resolution, and systematically manipulated the size of the attentional cue: A bar of different lengths (Experiment 1) or a frame of different sizes (Experiments 2-3) indicated the target region in a texture segmentation display. Observers indicated whether a target patch region (oriented line elements in a background of an orthogonal orientation), appearing at a range of eccentricities, was present in the first or the second interval. We replicated the attentional enhancement of spatial resolution found with small cues; attention improved performance at peripheral locations but impaired performance at central locations. However, there was no evidence of gradual resolution decrement with large cues. Transient attention enhanced spatial resolution at the attended location when it was attracted to that location by a small cue but did not affect resolution when it was attracted by a large cue. These results indicate that transient attention cannot adapt its operation on spatial resolution on the basis of the size of the attentional cue.     

The eccentricity effect: Target eccentricity affects performance on conjunction searches

The serial pattern found for conjunction visual-search tasks has been attributed to covert attentional shifts, even though the possible contributions of target location have not been considered. To investigate the effect of target location on orientation × color conjunction searches, the target’s duration and its position in the display were manipulated. The display was present either until observers responded (Experiment 1), for 104 msec (Experiment 2), or for 62 msec (Experiment 3). Target eccentricity critically affected performance: A pronounced eccentricity effect was very similar for all three experiments; as eccentricity increased, reaction times and errors increased gradually. Furthermore, the set-size effect became more pronounced as target eccentricity increased, and the extent of the eccentricity effect increased for larger set sizes. In addition, according to stepwise regressions, target eccentricity as well as its interaction with set size were good predictors of performance. We suggest that these findings could be explained by spatial-resolution and lateral-inhibition factors. The serial self-terminating hypothesis for orientation × color conjunction searches was evaluated and rejected. We compared the eccentricity effect as well as the extent of the orientation asymmetry in these three conjunction experiments with those found in feature experiments (Carrasco & Katz, 1992). The roles of eye movements, spatial resolution, and covert attention in the eccentricity effect, as well as their implications, are discussed.     

The Cognitive Interview and Lie Detection: a New Magnifying Glass for Sherlock Holmes?

The observation of serious deficiencies in the traditional police interview led Geiselman and colleagues to develop an alternative method of questioning. This method is known as the cognitive interview. The CI starts from the premise that the witness, victim or suspect wishes to cooperate. But, what happens if this is not the case? More seriously, what happens if he/she lies? The main aim of this study is to examine the differences between true and false statements, as a function of the interview technique employed (CI/STI). Participants were 73 students of the University of La Laguna. A 2×2 factorial design with the following variables was used: type of interview [traditional interview used in Spain by the Police (STI) and cognitive (CI)] and type of statement (true and false). The hypothesis was that the true and false accounts of witnesses would be qualitatively and quantitatively different independent of the type of interview used (STI/CI). Results confirmed the hypothesis. © 1997 by John Wiley & Sons, Ltd.     

The Interface Between Countertransference and Projective Identification in a Case Presented to Peer Supervision

This case report, presented to a supervision group, is a prenatal genetic counseling casethat caused me a great deal of emotional discomfort as the events unfolded. Thediscomfort originated during my first meeting with the couple for routine preamniocentesiscounseling and continued through later encounters. This case illustrates the process ofworking through countertransference and projective identification issues that may arise ingenetic counseling.

The role of attention and study time in explicit and implicit memory for unfamiliar visual stimuli

The effects of limited attentional resources and study time on explicit and implicit memory were studied using Schacter and Cooper’s possible and impossible objects in their recognition and object decision paradigm. In one experiment, when attention at study was limited by a flanking digits procedure, object recognition was diminished but object decision priming for possible objects was unaffected; in another experiment, limiting attention plus reducing stimulus study time impaired object recognition and eliminated object priming. Recognition memory and perceptual priming for previously unfamiliar visual stimuli were both influenced by attention, although to different degrees. The intervening variable of study time determined the degree to which priming was affected by attentional resources. These results support a limited capacity attentional model for both recognition and perceptual priming of unfamiliar visual stimuli, and they highlight the need for assessing the interaction of attentional resources and study time in explicit and implicit memory tasks.     

Aging and goal-directed emotional attention: distraction reverses emotional biases

Previous findings reveal that older adults favor positive over negative stimuli in both memory and attention (for a review, see Mather & Carstensen, 2005). This study used eye tracking to investigate the role of cognitive control in older adults' selective visual attention. Younger and older adults viewed emotional-neutral and emotional-emotional pairs of faces and pictures while their gaze patterns were recorded under full or divided attention conditions. Replicating previous eye-tracking findings, older adults allocated less of their visual attention to negative stimuli in negative-neutral stimulus pairings in the full attention condition than younger adults did. However, as predicted by a cognitive-control-based account of the positivity effect in older adults' information processing tendencies (Mather & Knight, 2005), older adults' tendency to avoid negative stimuli was reversed in the divided attention condition. Compared with younger adults, older adults' limited attentional resources were more likely to be drawn to negative stimuli when they were distracted. These findings indicate that emotional goals can have unintended consequences when cognitive control mechanisms are not fully available.     

Social identity and the recoding of reality : its relevance for cross-cultural psychology1

A methodological development in a current research program for the cross-cultural study of subjective identity is presented. The Associative Network Analysis (ANA) permits an idiographic exploration of cognitive mapping; it consists in generating the associative structure linked to various aspects of the individual's phenomenal world including the Self. Categorisation of social identity elements are seen as the result of recoding processes through which experience is transformed into images and thoughts and selectively stored in long term memory. Recoding rules expressing a link between individual values, strivings and perception of the external world can be determined.     

Voluntary Attention Enhances Contrast Appearance

ABSTRACT— Voluntary (endogenous, sustained) covert spatial attention selects relevant sensory information for prioritized processing. The behavioral and neural consequences of such selection have been extensively documented, but its phenomenology has received little empirical investigation. We asked whether voluntary attention affects the subjective appearance of contrast—a fundamental dimension of visual perception. We used a demanding rapid serial visual presentation (RSVP) task to direct endogenous attention to a given location and measured perceived contrast at the attended and unattended locations. Attention increased perceived contrast of suprathreshold stimuli and also improved performance on a concurrent orientation discrimination task at the cued location. We ruled out response bias as an alternative account of the pattern of results. Thus, this study establishes that voluntary attention enhances perceived contrast. This phenomenological consequence links behavioral and neurophysiological studies on the effects of attention.     

Parenthood and productivity: A study of demands, resources and family-friendly firms

We examine how the presence of children is related to women’s and men’s productivity. We hypothesize family demands, family resources, and family-friendly workplaces are also related to productivity. Productivity for 670 Alberta law firm lawyers is analyzed using a standardized measure of productivity referred to as billable hours. The results suggest that mothers with school-aged children are less productive than non-mothers, whereas fathers with preschool-aged children are more productive than non-fathers. While time spent on household and childcare tasks significantly reduces women’s productivity, we find little support for the benefits of family resources or working in a family-friendly firm for women. Rather, fathers seem to benefit more: family resources are positively related to their productivity and family-friendly benefits allow them more time for leisure. These results support the assumption that having children is negatively related to women’s productivity but challenges the belief that family-friendly policies are primarily beneficial only to mothers trying to balancing work and family.
