The influence of the immediate visual context on incremental thematic role-assignment: evidence from eye-movements in depicted events

Studies monitoring eye-movements in scenes containing entities have provided robust evidence for incremental reference resolution processes. This paper addresses the less studied question of whether depicted event scenes can affect processes of incremental thematic role-assignment. In Experiments 1 and 2, participants inspected agent-action-patient events while listening to German verb-second sentences with initial structural and role ambiguity. The experiments investigated the time course with which listeners could resolve this ambiguity by relating the verb to the depicted events. Such verb-mediated visual event information allowed early disambiguation on-line, as evidenced by anticipatory eye-movements to the appropriate agent/patient role filler. We replicated this finding while investigating the effects of intonation. Experiment 3 demonstrated that when the verb was sentence-final and thus did not establish early reference to the depicted events, linguistic cues alone enabled disambiguation before people encountered the verb. Our results reveal the on-line influence of depicted events on incremental thematic role-assignment and disambiguation of local structural and role ambiguity. In consequence, our findings require a notion of reference that includes actions and events in addition to entities (e.g. Semantics and Cognition, 1983), and argue for a theory of on-line sentence comprehension that exploits a rich inventory of semantic categories.     

When the ordinary seems unexpected: evidence for incremental physical knowledge in young infants

According to a recent account of infants' acquisition of their physical knowledge, the incremental-knowledge account, infants form distinct event categories, such as occlusion, containment, support, and collision events. In each category, infants identify one or more vectors which correspond to distinct problems that must be solved. For each vector, infants acquire a sequence of variables that enables them to predict outcomes within the vector more and more accurately over time. This account predicts that infants who have acquired only a few of the variables in a sequence should err in two ways in violation-of-expectation tasks: (1) they should view impossible events consistent with their incomplete knowledge as expected (errors of omission), and (2) they should view possible events inconsistent with their incomplete knowledge as unexpected (errors of commission). Many reports have shown that infants who have not yet identified a variable in an event category produce errors of omission: they fail to view impossible events involving the variable as unexpected. However, there has been no report revealing errors of commission in infants' responses to possible events. The present research examined whether 3- and 2.5-month-old infants, whose knowledge of occlusion events is very limited, would produce errors of commission as well as errors of omission when responding to these events. At 3 months of age, infants viewed as unexpected a possible event in which a tall cylinder became visible when passing behind a tall screen with a very large opening extending from its upper edge. At 2.5 months, infants viewed as unexpected a possible event in which a tall cylinder became visible when passing behind a tall screen with a very large opening extending from its lower edge. These findings provide a new kind of evidence for the incremental-knowledge account, and more generally for the notion that infants, like older children and adults, engage in rule-based reasoning about physical events.     

父母教养行为与青少年早期抑郁的关系：多基因与负性生活事件的调节作用

以745名青少年为被试,采用多基因×多环境设计,考察COMT Val158Met、5-HTR1A C-1019G和BDNF Val66Met基因多态性的多基因累加得分与负性生活事件在父母教养行为与青少年早期抑郁之间的调节作用及其性别差异。结果发现,多基因累加得分与负性生活事件仅能显著调节父亲积极教养行为对青少年抑郁的预测作用,且该调节作用只存在于男青少年群体中。研究结果丰富了抑郁的多基因遗传机制研究,为制定青少年早期抑郁的干预措施提供了理论依据。     

Perceived COVID-induced racism and contextual predictors of fear and psychological distress among Black men

The present study examined if Black men's perceptions of COVID-induced racism (i.e., the extent to which racism increased during the beginning months of the COVID-19 pandemic) were associated with their reported fear of COVID-19 and psychological distress. Self-report COVID-related variables and psychological distress data from 231 Black men in the U.S. were analyzed alongside archival percentages of confirmed cases and deaths by participants' county at the time of participation. Hierarchical regressions identified perceptions of COVID-induced racism as a significant predictor of Black men's psychological distress over and above contextual (e.g., county-level COVID-19 case %) and individual-level predictors (i.e., perceived race-related infection risk and self-reported COVID-related stressful life events). This work contributes to the growing literature on health inequities during the COVID-19 pandemic with a snapshot of Black men's experiences during the COVID-19 and racism pandemics of 2020 in the U.S.     

Children of alcoholics, negative life events, and early experimentation with drugs

Questionnaires were completed by sixth-grade students and their parents in order to assess differences between children of alcoholics (COAs) and their peers, as well as the relations between family environment and children's experimentation with alcohol, drugs, and tobacco. Social competence and problematic behavior were also explored. The best predictors of early experimentation with alcohol, drugs, and tobacco were the experience of negative life events, family conflict, and lack of family cohesion, but not COA status per se. Differences were found between COAs and non-COAs in respect to family structure, parent education levels, and family environment. COAs were found to be significantly more likely than their peers to experiment with tobacco, but not alcohol or drugs. They also had a tendency to engage more frequently in delinquent behavior. Recommendations for future research and implications for preventive activities are discussed.     

Development of a diary for use with ambulatory monitoring of mood,activities, and physiological function

This paper describes three studies developed and providing preliminary validation for a pocket-size, self-monitoring diary suitable for use infield research on relationships among psychological states, activities, and physiological events. In the first study, a principal-components analysis of the diary's mood and cognition scales yielded three factors—negative affect, engagement, and predictability. These showed moderate concordance across two samples. In the second study, diary self-ratings of events, moods, and cognitions were shown to be meaningfully correlated with ratings made by spouse observers, providing evidence of concurrent validity of the diary. In the third study, diary ratings made by the same subjects at home, at work, and in other locations differed from each other in expected ways, providing evidence for discriminative validity. Modifications to the diary are suggested, and possible uses and limitations of the instrument are discussed.This research was supported by USUHS protocol RO7233 and a grant from the John D. and Catherine T. MacArthur Foundation. The opinions and assertions expressed herein are those of the authors and should not be construed as reflecting those of the USUHS or the Department of Defense.     

The impact of variability and prechoice experience on taking safety measures: The case of security updates

The goal of this research is to clarify the conditions that trigger reluctance to take cost-effective safety measures. We present three experiments. In two of the experiments, the participants were asked to operate a simulated system for 20 periods, each with 10 trials. They could “update the system” to eliminate the risk of a “security failure” that led to a loss of 100 points. The updating cost was either fixed (at 10 points) or variable (initially 10 points, and some probability of free—0 points—updates). The optimal strategy prescribed updating at the first opportunity. Another experiment focused on one-shot decision under risk. The results highlight two factors that reduce the tendency to update and impair performance: cost variability and prechoice experience. Importantly, we show that the negative impact of cost variability is the product of two tendencies. First, experiencing periods with free updates slowed learning to select the optimal policy. Second, in many cases, the participants behaved as if they plan to update when the cost of updating is low but forget to do so. The results suggest that security can be enhanced by asking users to select a default updating policy before gaining experience and by replacing “free updates” with automatic updates. Information concerning the existence of automatic updates reduced manual updating, but this effect was eliminated by experience.     

Anxiety after remembering stressful academic versus brush with death events: The moderating roles of future time perspective and personal intimacy

This study examines: (i) whether recalling stressful autobiographical events results in anxiety, (ii) the relation of memory qualities to anxiety, and (iii) the relation of future time perspective and personal intimacy to experiencing anxiety. Participants (N = 120) completed Future Time Perspective, Personal Intimacy and State Anxiety scales. They were randomly assigned to recall a brush with death, a stressful academic deadline, or a no-stress control. Memory qualities (vividness and significance) were assessed. As expected, recalling stressful events resulted in anxiety with more personally significant events related to higher anxiety. Having a more open-ended future time perspective related to lower anxiety after recalling a stressful academic deadline, whereas greater personal intimacy predicted lower anxiety after recalling a brush with death. Findings are discussed in terms of factors that may serve to moderate the link between stressful memories and the experience of anxiety.
