Contingent attentional capture or delayed allocation of attention?

Under certain circumstances, external stimuli will elicit an involuntary shift of spatial attention, referred to as attentional capture. According to the contingent involuntary orienting account (Folk, Remington, & Johnston, 1992), capture is conditioned by top-down factors that set attention to respond involuntarily to stimulus properties relevant to one's behavioral goals. Evidence for this comes from spatial cuing studies showing that a spatial cuing effect is observed only when cues have goal-relevant properties. Here, we examine alternative, decision-level explanations of the spatial cuing effect that attribute evidence of capture to postpresentation delays in the voluntary allocation of attention, rather than to on-line involuntary shifts in direct response to the cue. In three spatial cuing experiments, delayed-allocation accounts were tested by examining whether items at the cued location were preferentially processed. The experiments provide evidence that costs and benefits in spatial cuing experiments do reflect the on-line capture of attention. The implications of these results for models of attentional control are discussed.     

Contingent orienting or contingent capture: A size singleton matching the target–distractor size relation cannot capture attention

In the present study, we examined whether a peripheral size-singleton distractor that matches the target–distractor size relation can capture attention and disrupt central target identification. Three experiments consistently showed that a size singleton that matches the target–distractor size relation cannot capture attention when it appears outside of the attentional window, even though the same size singleton produces a cuing effect. In addition, a color singleton that matches the target color, instead of a size singleton that matches the target–distractor size relation, captures attention when it is outside of the attentional window. Thus, a size-relation-matched distractor is much weaker than a color-matched distractor in capturing attention and cannot capture attention when the distractor appears outside of the attentional window.     

Attentional effects of negative faces: Top-down contingent or involuntary?

Recent research has substantiated that schematic negative faces are found more efficiently than positive faces among crowds of distractor faces of varying set sizes. The present study asks whether this relative search asymmetry (RSA) is intention driven or due to involuntary attentional capture. To that aim, participants were first tested in a condition in which negative and positive faces were searched for, and then in a condition in which negative or positive schematic faces appeared at chance level at the position of the target (valid trials) or of a distractor (invalid trials), the faces thus being task irrelevant (the 1/n paradigm). The expected search benefit for valid negative-face target trials most clearly occurred when participants searched for a target defined by a conjunction of color and position; when the target was defined either by an orientation or color singleton, we found rather weak or no evidence for involuntary attention capture by negative faces. We see the results as being (1) evidence that the RSA is partly based on stimulus-driven factors that occur independently of the intention to search for a positive or negative face, and (2) consistent with the assumption that the effects are mainly due to a more efficient rejection of positive-face than of negative-face distractors, rather than being due to attentional capture by the target     

“Non-Natural” Qualities in G.E. Moore: Inherent or Contingent?

G.E. Moore's theory of the nature of the quality referred to by the word good asserts that this quality is non-natural. If it is, further, supposed that this non-natural quality belongs necessarily and exclusively to those events, human acts, entities, etc., which possess certain strictly determined natural qualities, and those qualities only, then it becomes difficult to explain the relation and the supposed interdependence allegedly existing between the two so disparate categories of qualities. This paper purports to show that, in fact, any mutual dependence of natural and non-natural qualities, including the causal one, is unconceivable. To deny this would allow no less but the possibility of deriving an ought from an is. A final consequence of this is that a non-natural quality, denoted by the predicate good, does, in fact, attach to a strictly delineated and limited morally relevant behaviour (and whatever else we may consider morally relevant), and to it only. But it is attached there in randomly; it is contingent, not inherent; it is there without regard to, and not as a consequence of, the natural qualities of what is the subject of moral judgment ... whether we like it or not.     

What is top-down about contingent capture?

In the present study, we explored the mechanisms involved in the contingent capture phenomenon, using a variant of the classic precuing paradigm of Folk, Remington, and Johnston (1992). Rather than keeping the target fixed over a whole block of trials (as has traditionally been done with contingent capture experiments), we encouraged participants to adopt a top-down set before each trial. If top-down attentional set determines which property captures attention, as is claimed by the contingent capture hypothesis, one would expect that only properties that match the top-down set would capture attention. We showed that even though participants knew what the target would be on the upcoming trial, both relevant and irrelevant properties captured attention (Experiment 1). An intertrial analysis (Experiments 1 and 2) showed that previous contingent capture findings may, to a large extent, be explained by intertrial priming. In addition, when participants were further forced into adopting the required top-down set (Experiments 3 and 4), irrelevant cues were suppressed, suggesting that top-down control might operate through disengagement of attention from the location of a property that does not match top-down goals. The present findings suggest that top-down control and intertrial priming make their own distinct contributions to the contingent capture phenomenon.     

Forgiveness and marital quality: Precursor or consequence in well-established relationships?

Two exercises involving gratitude and uplifting music were tested for their ability to improve well-being in self-critical and needy individuals. In this study, 772 adults completed measures of depressive symptoms, physical symptoms, happiness, and self-esteem and then practiced the gratitude, music, or control exercise (recalling early childhood memories) for 1 week. Follow-up measures were administered after the intervention period, and 1, 3, and 6 months later. Participants in both the gratitude and the music condition reported greater increases in happiness over time than participants in the control condition. Self-critics were particularly responsive to the gratitude intervention, whereas needy individuals found the exercises ineffective and even detrimental to their self-esteem. These results highlight the importance of identifying individual differences in response to positive psychology exercises.     

Is service climate strength beneficial or detrimental for service quality delivery?

This study examines whether climate strength has a direct, moderating, or curvilinear effect in the relationship between service climate and customer service quality perceptions. To this end, we carried out cross-sectional and lagged empirical studies in the Spanish hospitality sector. Our cross-sectional results confirmed that high climate strength in managerial practices fosters a positive impact of managerial practices on customer service quality evaluations. However, other results related to customer orientation of services question the idea that service climate strength is always a precursor of service quality. High climate strength in customer orientation enhanced the negative relationship between customer orientation and functional service quality in a cross-sectional study, and between customer orientation and relational service quality in a lagged study. In addition, an examination of curvilinear effects of climate strength revealed an inverted U-shaped relationship between climate strength in customer orientation and relational service quality over time. The article concludes with a discussion of these results.

Phenomenologizing with A Hammer: Theory or Practice?

As a contribution towards clearing the ground for a new phenomenological evaluation of the essence of science, in this paper I present a critique of Heidegger's argument in Being and Time for the priority of Zuhandenheit to Vorhandenheit. I argue that Heidegger's notion of presence-at-hand is incoherent, conflating Husserl and Descartes, and that this general analysis has serious phenomenological flaws. Contrary to Heidegger, I maintain that there is a form of exploratory, theoretical activity including causal inquiry which is prior to the type of practical activity entailed by readiness-to-hand. Consideration of this exploratory activity points us in the direction of an alternate conception of the genesis and essence of theory.     

Do individual differences in sociosexuality represent genetic or environmentally contingent strategies? Evidence from the Australian twin registry

Although men are substantially more interested than women in casual sex, there is ample variation in this trait (sociosexuality) within both sexes. One theory hypothesizes that within-sex sociosexual variation results from genetic variation maintained by frequency-dependent selection. If so, sociosexuality should be substantially heritable. A competing theory is that children acquire their mating strategy after observing their parents' relationship. By this theory, sociosexuality should reveal a strong shared environmental component. The authors studied genetic and environmental influences on sociosexuality using a large, representative volunteer twin sample. Parental marital instability was modestly associated with sociosexuality, but this could have been due to either genetic or environmental factors. Consistent with genetic theory, familial resemblance appeared primarily due to additive genetic rather than shared environmental factors.     

Berkeley’s Contingent Necessities

The paper provides an account of necessary truths in Berkeley based upon his divine language model. If the thesis of the paper is correct, not all Berkeleian necessary truths can be known a priori.

Does home life interfere with or facilitate job performance?

The study examines whether home life influences inrole and extrarole job performance in positive or negative ways. We hypothesized that home resources would have a direct positive effect on job performance, and an indirect relationship through home–work facilitation (HWF). Home demands were predicted to negatively affect job performance through home–work interference (HWI). These hypotheses were tested on a sample of 190 male employees. In addition to employees' self-reports, wives rated their own home demands and resources (these were used as controls), and co-workers rated the men's HWI, HWF, and job performance. Results partially supported the hypotheses. Men's home demands and resources were related to self-rated HWI and HWF respectively, whereas co-worker ratings of HWI and HWF were associated with inrole and extrarole performance respectively. Men's home resources also had a direct relationship with inrole and extrarole performance. There was no convincing evidence that HWI and HWF acted as mediators in these relationships. Taken together, the positive influence of home life on job performance was stronger than the negative one.     

Do self-reported decision styles relate with others’ impressions of decision quality?

Research has demonstrated the usefulness of decision styles for predicting various performance-related criteria. It is still unclear, however, which particular styles are associated with a general tendency to make high-quality decisions. Participants (n = 168) completed a common measure of five decision styles, along with a measure of the traits in the five-factor model of personality. Self and peer evaluations of general decision quality were obtained as performance criteria. Results showed that specific decision styles predicted variance in both measures of decision quality. And, there was clear evidence for incremental validity for specific decision styles when self-ratings were predicted. In the context of past research, this study supports a primary focus on rational or analytical styles for understanding and predicting decision success.     

Are self-enhancing cognitions associated with healthy or unhealthy biological profiles?

Self-enhancement is variously portrayed as a positive illusion that can foster health and longevity or as defensive neuroticism that can have physiological-neuroendocrine costs. In a laboratory stress-challenge paradigm, the authors found that high self-enhancers had lower cardiovascular responses to stress, more rapid cardiovascular recovery, and lower baseline cortisol levels, consistent with the positive illusions predictions and counter to the predictions of the defensive neuroticism position. A second set of analyses, replicating the "illusory mental health paradigm" (J. Shedler, M. Mayman, & M. Manis, 1993), also did not support the defensive neuroticism hypothesis. The association between self-enhancement and cortisol was mediated by psychological resources; analyses of the cardiovascular results provided no definitive mediational pathway. Discussion centers on the potential stress-buffering effects of self-enhancing beliefs.     

Children's understanding of sentences with contingent relations: Why are temporal and conditional connectives so difficult?

Children aged 5-, 7-, and 9 were tested on two different tasks to assess their understanding of sentences containing the connectives “when,” “as soon as,” “before,” “after,” “if,” “if-not,” “unless,” and “unless-not.” The results revealed significant improvement between the ages of 5 and 7. This improvement was attributed, in part, to an increased ability to retain information expressed in subordinate clauses. At all age levels, however, the connectives “unless” and “unless-not” were consistently misinterpreted; “unless” was treated as its polar opposite “if,” and “unless-not” was treated as its polar opposite “if-not.”     

Free Gift with Purchase: Promoting or Discounting the Brand?

Two experiments examine the process by which free gift promotions serve as a source of information about the underlying value of the product offered as a free gift. The value‐discounting hypothesis argues that by virtue of being offered as a free gift, products will be valued less as evinced by lower purchase intentions and a lower price that consumers are willing to pay for them. Conditions that inhibit the value‐discounting effect include the (a) presence of alternate price information to make judgments about the value of the gift, and (b) contextual information about the value of the promoted brand.     

Learning and adult neurogenesis: survival with or without proliferation?

Recent high quality papers have renewed interest in the phenomenon of neurogenesis within the adult mammalian brain. Many studies now show that neurogenesis can be modulated by environmental factors including physical activity, stress, and learning. These findings have considerable implications for neuroscience in general, including the study of learning and memory, neural network plasticity, aging, neurodegeneration, and the recovery from brain injury. Although new light has been shed on this field, many contradictory findings have been reported. Here we propose two principle issues which underlie these inconsistencies, with particular focus on the interaction between learning and neurogenesis. The first issue relates to the basic methodology of measuring the generation of new brain cells, i.e., proliferation, as compared to survival of the newly made cells. Mostly, measures of neurogenesis reported are a combination of proliferation and survival, making it impossible to distinguish between these separate processes. The second aspect is in regards to the role of environmental factors which can affect both proliferation and survival independently. Especially the interaction between stress and learning is of importance since these might counteract each other in some circumstances. Reviewing the literature while taking these issues into account indicates that, in contrast to some findings, cell proliferation in the dentate gyrus of the hippocampus as a result of learning cannot be ruled out yet. On the other hand, increased survival of granule cells in the dentate gyrus as a result of hippocampal-dependent learning has been clearly demonstrated. Moreover, this learning-induced survival of granule cells, which were born before the actual learning experience, might provide a molecular mechanism for the 'use it or lose it' principle.
