Feeling the future: experimental evidence for anomalous retroactive influences on cognition and affect

The term psi denotes anomalous processes of information or energy transfer that are currently unexplained in terms of known physical or biological mechanisms. Two variants of psi are precognition (conscious cognitive awareness) and premonition (affective apprehension) of a future event that could not otherwise be anticipated through any known inferential process. Precognition and premonition are themselves special cases of a more general phenomenon: the anomalous retroactive influence of some future event on an individual's current responses, whether those responses are conscious or nonconscious, cognitive or affective. This article reports 9 experiments, involving more than 1,000 participants, that test for retroactive influence by "time-reversing" well-established psychological effects so that the individual's responses are obtained before the putatively causal stimulus events occur. Data are presented for 4 time-reversed effects: precognitive approach to erotic stimuli and precognitive avoidance of negative stimuli; retroactive priming; retroactive habituation; and retroactive facilitation of recall. The mean effect size (d) in psi performance across all 9 experiments was 0.22, and all but one of the experiments yielded statistically significant results. The individual-difference variable of stimulus seeking, a component of extraversion, was significantly correlated with psi performance in 5 of the experiments, with participants who scored above the midpoint on a scale of stimulus seeking achieving a mean effect size of 0.43. Skepticism about psi, issues of replication, and theories of psi are also discussed.     

The role of context in preschool learning: a multilevel examination of the contribution of context-specific problem behaviors and classroom process quality to low-income children's approaches to learning

Research suggests that promoting adaptive approaches to learning early in childhood may help close the gap between advantaged and disadvantaged children. Recent research has identified specific child-level and classroom-level variables that are significantly associated with preschoolers' approaches to learning. However, further research is needed to understand the interactive effects of these variables and determine whether classroom-level variables buffer the detrimental effects of child-level risk variables. Using a largely urban and minority sample (N = 275) of preschool children, the present study examined the additive and interactive effects of children's context-specific problem behaviors and classroom process quality dimensions on children's approaches to learning. Teachers rated children's problem behavior and approaches to learning and independent assessors conducted classroom observations to assess process quality. Problem behaviors in structured learning situations and in peer and teacher interactions were found to negatively predict variance in approaches to learning. Classroom process quality domains did not independently predict variance in approaches to learning. Nonetheless, classroom process quality played an important role in these associations; high emotional support buffered the detrimental effects of problem behavior, whereas high instructional support exacerbated them. The findings of this study have important implications for classroom practices aimed at helping children who exhibit problem behaviors.     

The cortisol awakening response: Associations with trait anxiety and stress reactivity

This study investigated the extent to which trait anxiety and state anxiety in response to stress are associated with the cortisol awakening response (CAR).Fifty-one healthy participants were recruited. State anxiety measures were taken in anticipation of and during a laboratory stressor. Salivary cortisol levels were measured immediately upon awakening (at 0, 15, 30, and 45 min) on two consecutive mornings. Cortisol awakening response was assessed by the area under the curve with respect to zero (AUC_G).The magnitude of the CAR was found to be negatively associated with both trait anxiety and anticipatory anxiety. Moreover, regression analysis showed that the effects of trait anxiety on the AUC_G were mediated by anticipatory anxiety.These results suggest that the CAR is influenced by trait anxiety. Moreover, the effect of trait anxiety on the CAR seems to operate by impacting on psychological stress reactivity (i.e., anticipatory anxiety).     

Reading and Empathy

The relationship between reading and empathy was explored. Controlling for GPA and gender, reading variables were hypothesized as related to empathy; the relationship was expected to differ for males and females. For the complete sample, affective components were related to GPA but not reading. Perspective taking was related to reading appreciation but not GPA. For females, reading appreciation was related to perspective taking and empathic concern. For males, GPA and non-fiction reading were positively related, but both were negatively related to empathic concern. Results suggest reading may promote both academic achievement and social development. Findings and social implications are discussed.     

The many faces of stereotype threat: Group- and self-threat

Contending with negative intellectual stereotypes has been shown to depress the academic performance of targets of the stereotypes [Steele, C. M. (1997). A threat in the air: How stereotypes shape intellectual identity and performance. American Psychologist, 52, 613-629]. The present paper examines whether women’s mathematics performance is differentially affected by the concern of confirming that a negative stereotype is true of the self (self-threat), than by the concern of confirming that the stereotype is true of their gender (group-threat). In two studies we independently manipulated these different threats for women taking a mathematics test. Gender identification moderated the effect of group-threats on test performance; only women highly identified with their gender underperformed. The performance of less gender-identified women was unaffected by group-threats. In contrast, gender identification did not moderate the effect of self-threats—both high- and low-identified women underperformed. The results of these studies suggest that women’s math performance is differentially affected by the source of the threat.     

Ordered categories and additive conjoint measurement on connected sets

Suppose that a binary relation is given on a n-fold Cartesian product. The study of the conditions guaranteeing the existence of n value functions such that the binary relation can be additively represented is known as additive conjoint measurement. In this paper we analyze a related problem: given a partition of a Cartesian product into r ordered categories, what conditions do ensure the representability of the partition in an additive model?     

The Near-Death Experience: An Integration of Cultural, Spiritual, and Physical Perspectives

The near-death experience (NDE) has been studied extensively from two conflicting perspectives: that the NDE is a glimpse into an after-death state and that it is the result of a dying brain. Of late a third perspective has emerged, that of NDEs being culturally determined. I propose an integrated model in which all three perspectives are viewed with equal weight.     

Basic Personality Inventory clinical and validity scales: Stability and internal consistency

A sample of 71 incarcerated adult male inmates was used to investigate the stability and internal consistency for the clinical and validity scales of the Basic Personality Inventoiy. One month test-retest stability coefficients for the clinical scales ranged from .53 to .77. KR-20 reliabilities ranged from .61 to .86 on each occasion. With the exception of the longer perseveration scales, stability was also reasonable for the validity scales. Overall, the Basic Personality Inventory clinical and validity scales demonstrated favorable stability and reliability in an inmate population.This research was supported by a STEP grant from the Alberta Government.
