Nonconscious acquisition of information.

The authors review and summarize evidence for the process of acquisition of information outside of conscious awareness (covariations, nonconscious indirect and interactive inferences, self-perpetuation of procedural knowledge). Data indicate that as compared with consciously controlled cognition, the nonconscious information-acquisition processes are not only much faster but are also structurally more sophisticated, in that they are capable of efficient processing of multidimensional and interactive relations between variables. Those mechanisms of nonconscious acquisition of information provide a major channel for the development of procedural knowledge that is indispensable for such important aspects of cognitive functioning as encoding and interpretation of stimuli and the triggering of emotional reactions.     

Smells like sib spirit: kin recognition in three-spined sticklebacks (<Emphasis Type="Italic">Gasterosteus aculeatus</Emphasis>) is mediated by olfactory cues

The ability to recognise kin has been demonstrated in several animal species. However, the mechanisms of kin recognition often remain unknown. The most frequently discussed sensory modalities to recognise kin are visual, olfactory and acoustical cues. Three-spined sticklebacks (Gasterosteus aculeatus) are able to differentiate between kin and non-kin when presented visual and olfactory cues combined. To elucidate, which cues they use to recognise kin female sticklebacks were given the choice between two identical computer animations of courting stickleback males. Next to one animation, water conditioned by a brother was added, while near the other, water from an unrelated male was added. In half of the experiments, the brother was familiar while in the other half he was unfamiliar to the female. Both scenarios were carried out with both outbred and inbred fish. The results showed that the females adjusted their choice behaviour according to relatedness. Furthermore, they were able to recognise both familiar as well as unfamiliar brothers. Inbreeding did not affect this ability. Hence, three-spined sticklebacks are able to recognise their relatives using olfactory cues alone. The cognitive mechanisms underlying this ability were independent from familiarity and not impaired by inbreeding.     

无意识目标：激活与追求

目标自动激活模型认为,目标是行为满意状态或结果在个体头脑中的表征,它能够通过相关情境自动激活。无意识目标的激活方式有语义激活、工具激活和人际激活。无意识目标追求与有意识目标追求在目标实现、目标投射和动机特征方面相似,但其行为产生机制有所不同。未来研究应该对无意识目标的机制及其具体应用进行深入的探讨     

The effects of reward and punishment in violent video games on aggressive affect, cognition, and behavior

Three experiments examined the effects of rewarding and punishing violent actions in video games on later aggression-related variables. Participants played one of three versions of the same race-car video game: (a) a version in which all violence was rewarded, (b) a version in which all violence was punished, and (c) a nonviolent version. Participants were then measured for aggressive affect (Experiment 1), aggressive cognition (Experiment 2), and aggressive behavior (Experiment 3). Rewarding violent game actions increased hostile emotion, aggressive thinking, and aggressive behavior. Punishing violent actions increased hostile emotion, but did not increase aggressive thinking or aggressive behavior. Results suggest that games that reward violent actions can increase aggressive behavior by increasing aggressive thinking.

Automatic effects of deviancy cues on creative cognition

Three experiments test the existence of an automatic deviancy‐creativity link. Using a lexical decision task, in Experiment 1 we found a semantic link between deviancy and creativity words in that decision times for creativity‐related words were enhanced after subliminal deviancy priming. In Experiment 2, participants were led to think about either a punk or an engineer and afterwards were administered creative insight and analytical reasoning problems. According to a pretest, punks and engineers were judged as differing in uniqueness but not in creativity. Participants given ‘punk’ priming solved more creative insight problems and fewer analytical reasoning problems than those given ‘engineer’ priming. In Experiment 3, participants were incidentally exposed to abstract artworks symbolically expressing either the concept of conformity or deviancy and were subsequently asked to solve a creative generation task. Exposure to the artwork representing deviancy led to generation of more creative solutions than exposure to that representing conformity. Copyright © 2005 John Wiley & Sons, Ltd.     

Vaginal scent marking: effects on ultrasonic calling and attraction of male golden hamsters

Male hamsters were tested for their responses to areas that had been scent marked by intact or vaginectomized females to determine the effects of naturally deposited vaginal secretions on male behavior. In the first experiment males produced more ultrasonic courtship calls when investigating areas marked by intact females than areas scented by vaginectomized females, demonstrating that vaginal marks facilitate such calling. In a wind-tunnel preference test situation in which scent-marked alleys and clean alleys served as sources of odor, males approached the scented alley first if it had been freshly marked by intact females but not if it had been scented by vaginectomized females or other males. Thus, the odors of vaginal marks are sufficient to attract males over short distances. After males entered these alleys they showed a preference for odors of both intact and vaginectomized females over no odors, but still spent significantly more time investigating the odors of intact females than those of vaginectomized females. These experiments indicate that vaginal secretions are one of the primary cues that elicit male courtship calling, and the small quantities of vaginal secretions deposited by females in vaginal marks are sufficient to elicit ultrasonic calling and attract males over short distances. Thus it is likely that vaginal scent marking and ultrasonic calling by females interact to facilitate attraction and location of mates during courtship.     

The effects of precocious adrenarche on cognition and hemispheric specialization

Cognitive skills were assessed in 13 females with a history of precocious adrenarche (PA). They were of average intelligence. In terms of lateralized cognitive skills, PA had no effect on verbal fluency. The spatial abilities of females with a history of PA, who had reached gonarche (were fully pubertal), were inferior to those of females tested in the midst of PA and to population controls. The physiologic/hormonal changes associated with normal adrenarche may curtail further specialization of the right hemisphere, resulting in a relative spatial deficit among females in general, who as a group reach adrenarche earlier than males. This spatial performance deficit is exaggerated in females with PA.     

The effects of goal difficulty on physiological arousal, cognition, and task performance.

Two laboratory experiments with 117 undergraduate students were conducted to examine (a) the effect of assigned goal difficulty on arousal (self-report and heart rate), cognition (perceived norm, self-efficacy strength, and personal goal), and behavioral (task performance) measures and (b) the role of heart rate as a mediator of the goal-difficulty-performance relation. All Ss performed a task requiring cognitive and physical responses. Results of both experiments demonstrated that assigned goal difficulty affected heart rate, cognition, and task performance and that heart-rate change was positively related to the cognitive and behavioral measures. Regression analyses suggested that a cognitive-affective mechanism may mediate the goal-difficulty-performance relation. Discussion is focused on the theoretical and practical implications of integrating an arousal concept within goal-setting theory.

Threat of bodily harm has opposing effects on cognition

Several theoretical frameworks have suggested that anxiety/stress impairs cognitive performance. A competing prediction is made by attentional narrowing models that predict that stress decreases the processing of task-irrelevant items, thus benefiting performance when task-irrelevant information interferes with behavior. Critically, previous studies have not evaluated these competing frameworks when potent emotional manipulations are involved. Here, we used threat of bodily harm preceding a color-word Stroop task to test these claims. We found a basic effect of threat consisting of a slowing down of performance during neutral Stroop trials. Furthermore, both facilitation and interference scores were affected by threat of shock in a way that was consistent with a reduced-distractor effect. Taken together, we interpret our findings in terms of two opposing effects of stress on cognitive performance. Although partly consistent with the attentional narrowing hypothesis, both resource models and cognitive breadth models require revision in order to account for the results.     

Maternal depression: Effects on social cognition and behavior in parent-child interactions

The social interactions of depressed and nondepressed mothers and their preschool-age children were observed and mothers' perceptions of child behavior assessed. Depressed mothers, as a group, exhibited more negative behavior than controls; however, no differences were found for maternal positive behavior or contingent responding. There was a high degree of reciprocity between child and mother behavior in both groups and there was a trend for children of the depressed mothers to be more negative than the control children. The results with cognitive measures were consistent with depressive realism in perception of social interactions: Depressed mothers recalled more negative child behavior than nondepressed mothers; however, these perceptions paralleled the observed interactions. Overall, the results suggest that maternal depression is associated with negative parent-child interactions and more negative, albeit fairly accurate, perceptions of child behavior.This study is based on portions of a doctoral dissertation completed in the Department of Psychology at the University of Iowa. I appreciate the guidance of my advisors Michael O'Hara and Donald K. Routh and committee members Leonard Feldt, John Knutson, and Sue Rosner.     

The intrinsic link between motor behavior and temporal cognition

The debate about the cognitive mechanisms behind human temporal processing has raged for decades without a clear resolution. The theory presented here describes a different perspective to the traditional accounts on the issue, namely, that motor behaviors or sequences of motor behaviors provide a means of reproducing time intervals. Evidence behind this perspective includes tapping strategies (exemplified by musicians), counting strategies, and neuropsychological results showing activation of motor areas during temporal cognitive tasks. I propose that motor behaviors aid human timing by offering a set of processes that consistently take a set amount of time to accomplish. Motor behaviors also allow segmentation of larger intervals into smaller intervals that are easier to estimate. I conclude with a discussion of implications of this perspective on temporal cognition.     

The effects of stress and stress hormones on human cognition: Implications for the field of brain and cognition

In this review, we report on studies that have assessed the effects of exogenous and endogenous increases in stress hormones on human cognitive performance. We first describe the history of the studies on the effects of using exogenous stress hormones such as glucocorticoids as anti-inflammatory medications on human cognition and mental health. Here, we summarize the cases that led to the diagnosis of glucocorticoid-induced 'steroid psychosis' in human populations and which demonstrated that these stress hormones could thus cross the blood-brain barrier and access the brain where they could influence cognition and mental health. We then summarize studies that assessed the effects of the exogenous administration of glucocorticoids on cognitive performance supported by the hippocampus, the frontal lobes and amygdala. In the second section of the paper, we summarize the effects of the endogenous release of glucocorticoids induced by exposure to a stressful situation on human cognition and we further dissociate the effects of emotion from those of stress on human learning and memory. Finally, in the last section of the paper, we discuss the potential impact that the environmental context to which we expose participants when assessing their memory could have on their reactivity to stress and subsequent cognitive performance. In order to make our point, we discuss the field of memory and aging and we suggest that some of the 'age-related memory impairments' observed in the literature could be partly due to increased stress reactivity in older adults to the environmental context of testing. We also discuss the inverse negative correlations reported between hippocampal volume and memory for young and older adults and suggest that these inverse correlations could be partly due to the effects of contextual stress in young and older adults, as a function of age-related differences in hippocampal volume.     

The Nonconscious Nature of Power: Cues and Consequences

Power – asymmetric control over valued resources – is a fundamental dimension of social relations. Classical conceptualizations of power emphasize its conscious nature. In this review, we reveal how power often operates nonconsciously and identify the different methods and paradigms used to activate or create a psychological sense of power outside of conscious awareness. First, we establish that cues of power are often attended to nonconsciously, which explains why people can be so accurate at determining their own and others’ level of power yet so inaccurate at identifying the specific cues diagnostic of possessing power. Second, we discuss how people are often unaware of how the possession of power fundamentally alters basic psychological and behavioral tendencies and describe the range of methodologies – roles, cues, episodic recall, conceptual priming – used to identify the nonconscious effects of power. Power produces two broad types of effects: It increases abstraction in thought and approach in behavior, both of which make individuals more focused on their own goals and internal states. Like other psychological constructs and processes, even ones that are inherently social and relational, power’s cues and consequences do not have to be conscious for its profound influence on basic psychological and interpersonal processes to emerge. We discuss the implications of the nonconscious nature of power for limiting the corrupting, dark side often revealed among the powerful.     

A warm heart and a clear head. The contingent effects of weather on mood and cognition

Prior studies on the association between weather and psychological changes have produced mixed results. In part, this inconsistency may be because weather's psychological effects are moderated by two important factors: the season and time spent outside. In two correlational studies and an experiment manipulating participants' time outdoors (total N = 605), pleasant weather (higher temperature or barometric pressure) was related to higher mood, better memory, and "broadened" cognitive style during the spring as time spent outside increased. The same relationships between mood and weather were not observed during other times of year, and indeed hotter weather was associated with lower mood in the summer. These results are consistent with findings on seasonal affective disorder, and suggest that pleasant weather improves mood and broadens cognition in the spring because people have been deprived of such weather during the winter.     

Behavioral skills training in scent detection research: Interactions between trainer and animal behavior

Animal trainers working in scent detection programs are responsible for arranging training contingencies as well as for observing and recording animal behavior. We provided behavioral skills training (BST) to animal trainers working with scent detection rats to improve the treatment integrity of scent‐detection research sessions. We evaluated the trainers' behavior at baseline and during the sequential introduction of each component of BST (instructions, modeling, and feedback). We observed incremental improvements in treatment integrity with the introduction of each BST component. Posttraining probes revealed that these improvements were sustained at least 3 weeks post‐BST. As the trainers' behavior was modified during BST, we observed decrements in measures of rat performance. We discuss the nature of these interactions and their implications for the use of BST in scent detection research and in situations in which intervention with one party produces concomitant effects on the behavior of another.     

Nonconscious influences of religion on prosociality: a priming study

Past literature on the automaticity of social behavior indicates that priming a concept automatically activates related behavioral schemas. In the two present studies we examined the impact of religion on prosociality. In the first study, we tested the impact of subliminal priming of religious concepts on prosocial behavior intentions. We found a main effect of this priming, moderated by valence: prosocial behavior tendencies were stronger when positive religious words had previously been subliminally primed. In the second study, we examined the accessibility of prosocial concepts, after the supraliminal activation of religion. Indeed, we found that not only were religion‐related attributes more accessible when primed, but positive religious primes were also able to activate prosocial concepts. While previous research has shown the religion‐prosociality link at the explicit level and in terms of the role of individual religiousness, these results indicate that religious concepts by themselves can nonconsciously activate prosocial behavioral schemas.
