Age Differences in Affective Well-Being: Context Matters

The study of emotion across the adult lifespan requires an understanding of how life circumstances change with age. With this knowledge, we can predict when age is related to increases in affective well-being and when age no longer confers such benefits. In the current paper, we review research that finds age-related stability and even increases in affective well-being, as well as age-related strengths in several emotion regulation strategies. We introduce the theory of Strength and Vulnerability Integration to predict age-related patterns in emotional experience across the adult lifespan, and to identify situations when age will no longer be related to improved emotion-related outcomes. We suggest that only by understanding the context of daily life can we predict when and how age is related to affective well-being.     

Flexible working memory representation of the relationship between an object and its location as revealed by interactions with attention

Working memory (WM) selectively maintains a limited amount of currently relevant information in an active state to influence future perceptual processing, thought, and behavior. The representation of the information held in WM is unknown, particularly the degree of separation between the representation of an object’s identity and its location. The present experiments examined the flexibility of object and location WM representations by measuring reaction times on a visual discrimination task during the delay period of a WM recognition task for object identities, locations, or both. The results demonstrate that during WM delay periods, attention is biased toward information that matches the current contents of WM. Attention is not biased toward information that was present in the encoded memory sample but not relevant for the memory recognition test. This specificity of the interaction between WM and attention applies to both the identity and the location of the remembered stimulus and to the relationship between an object and its location. The results suggest that when this relationship is necessary for task performance, WM represents an object and its identity in an integrated manner. However, if this relationship is not task relevant, the object and location information are represented in WM separately.     

Symbolic control of visual attention: Semantic constraints on the spatial distribution of attention

Humans routinely use spatial language to control the spatial distribution of attention. In so doing, spatial information may be communicated from one individual to another across opposing frames of reference, which in turn can lead to inconsistent mappings between symbols and directions (or locations). These inconsistencies may have important implications for the symbolic control of attention because they can be translated into differences in cue validity, a manipulation that is known to influence the focus of attention. This differential validity hypothesis was tested in Experiment 1 by comparing spatial word cues that were predicted to have high learned spatial validity (“above/below”) and low learned spatial validity (“left/right”). Consistent with this prediction, when two measures of selective attention were used, the results indicated that attention was less focused in response to “left/right” cues than in response to “above/below” cues, even when the actual validity of each of the cues was equal. In addition, Experiment 2 predicted that spatial words such as “left/right” would have lower spatial validity than would other directional symbols that specify direction along the horizontal axis, such as “←/→” cues. The results were also consistent with this hypothesis. Altogether, the present findings demonstrate important semantic-based constraints on the spatial distribution of attention.     

The effects of wording on the understanding and use of uncertainty information in a threshold forecasting decision

Many believe that information about small chances of severe weather would be useful to the general public for precautionary action. What is the best way to explain this kind of information to a non‐expert audience? The studies reported here investigated effects of framing (negative vs. positive), format (frequency vs. probability), likelihood (low vs. high) and compatibility (task‐match) on interpretation of verbal expressions of forecast uncertainty and on subsequent forecasting decisions. The crucial factor was the match between the verbal expression and the overall task goal. Errors increased when there was a mismatch between the expression (e.g. winds less than 20 knots) and the task (e.g. post an advisory when winds will exceed 20 knots). However, framing and format had little impact. We conclude that consideration of user expectations arising from the overall task goal is crucial in explaining uncertainty information to a naïve audience. Global expectations overpower other potential effects. Copyright © 2008 John Wiley & Sons, Ltd.     

Psychological contracts and their implications for commitment: A feature-based approach

Two studies were conducted to examine the link between employee perceptions of the psychological contract and their affective and normative commitments to the organization. The authors adapt a new approach to the study of psychological contracts by developing a generalizable measure of contract features (e.g., scope; time frame). In Study 1 (N = 301), the authors predicted and found that employees’ perceptions of the contract’s features contributed beyond perceptions of contract type (i.e., transactional; relational) and fulfillment to the prediction of affective and normative commitment. In Study 2 (N = 147), the features measure was refined and results from the first study were largely replicated. In both studies, affective and normative commitment were greater when employees viewed the contract as broad, trust-based, equal, negotiated, tangible, and long-term, and weaker when they saw it as unequal, imposed, and short-term. We also found evidence for patterns of features that correspond to transactional and relational contracts, as well as to recently proposed balanced contracts and I-Deals. Implications for theory and the management of psychological contracts are discussed.     

Differences in preschoolers’ and adults’ use of generics about novel animals and artifacts: A window onto a conceptual divide

Children and adults commonly produce more generic noun phrases (e.g., birds fly) about animals than artifacts. This may reflect differences in participants’ generic knowledge about specific animals/artifacts (e.g., dogs/chairs), or it may reflect a more general distinction. To test this, the current experiments asked adults and preschoolers to generate properties about novel animals and artifacts (Experiment 1: real animals/artifacts; Experiments 2 and 3: matched pairs of maximally similar, novel animals/artifacts). Data demonstrate that even without prior knowledge about these items, the likelihood of producing a generic is significantly greater for animals than artifacts. These results leave open the question of whether this pattern is the product of experience and learned associations or instead a set of early-developing theories about animals and artifacts.     

Frequency trajectory effects in Chinese character recognition: Evidence for the arbitrary mapping hypothesis

Frequency trajectory is a better measure to investigate age-limited learning effects than age of acquisition (AoA) ratings (Zevin, J. D., & Seidenberg, M. S. (2002). Age of acquisition effects in word reading and other tasks. Journal of Memory and Language, 47(1), 1-29). The current study uses frequency trajectory as a variable to investigate age-limited learning effects in Chinese character recognition, and tests predictions of the arbitrary mapping hypothesis as applied in a non-alphabetic writing system. In Experiment 1, regression analyses showed that, compared to rated AoA, frequency trajectory of characters was less affected by other lexical properties, and could explain a significant proportion of variance of AoA. In Experiment 2, the frequency trajectory and predictability from orthography to pronunciation of characters were orthogonally manipulated in a character naming task. The frequency trajectory effect appeared only for the arbitrary mapping condition. In Experiment 3, frequency trajectory and predictability from orthography to meaning of characters were manipulated in a semantic category judgment task. The frequency trajectory effects were found only when the mapping from orthography to semantic is less consistent. In summary, the study confirmed that AoA is a genuine factor affecting word processing, and the AoA effects were limited to those situations in which mapping between input and output representation was arbitrary. These results provide strong cross-linguistic evidence in support of the arbitrary mapping hypothesis.     

The Influence of Dysphoria on Reactivity to Naturalistic Fluctuations in Anger

Abstract We used an experience sampling methodology to explore the relationship between current symptoms of dysphoria and momentary mood fluctuations following everyday experiences of anger. Using PDA devices, participants rated their mood, ruminative cognitions, feelings of dependency, and stressful events 4 times per day for 1 week. We hypothesized and found that those higher in dysphoria would demonstrate a stronger link between anger and depressed mood than those who were lower in dysphoria. Those participants who reported higher initial dysphoria indicated more anger over the course of the week, a stronger within-person association between anger and depressed mood, and a slower recovery from anger experiences. Multilevel moderated mediation analyses indicated that the link between anger and depressed mood for those high in dysphoria is largely explained by a stronger carryover of anger from one assessment to the next and partially explained by greater increases in ruminative cognitions and feelings of dependency. The change in depressed mood appears to occur with increases in anger, specifically, and not other negative mood states. Our results extend previous research on the anger–depression relationship by investigating the short-term relationships between anger and depressed mood among those with varying levels of dysphoria.     

Two pathways to stimulus encoding in category learning?

Category learning theorists tacitly assume that stimuli are encoded by a single pathway. Motivated by theories of object recognition, we evaluated a dual-pathway account of stimulus encoding. The part-based pathway establishes mappings between sensory input and symbols that encode discrete stimulus features, whereas the image-based pathway applies holistic templates to sensory input. Our experiments used rule-plus-exception structures, in which one exception item in each category violates a salient regularity and must be distinguished from other items. In Experiment 1, we found discrete representations to be crucial for recognition of exceptions following brief training. Experiments 2 and 3 involved multisession training regimens designed to encourage either part- or image-based encoding. We found that both pathways are able to support exception encoding, but have unique characteristics. We speculate that one advantage of the part-based pathway is the ability to generalize across domains, whereas the image-based pathway provides faster and more effortless recognition.     

Specificity of cognitive and behavioral variables to Positive and Negative Affect

The Tripartite Model proposes that a combination of greater Negative Affect (NA) and reduced Positive Affect (PA) contributes to depressive symptoms. The purpose of this study was to test a model of affective experience in which cognitive variables (i.e., negative cognitions and appraisals) are uniquely related to NA but not PA, and in which behavioral variables (i.e., activity participation) are uniquely associated with PA but not NA. Participants included 88 spousal Alzheimer caregivers (mean age = 74 years). Multiple regression models, in which negative cognitions (i.e., helplessness, blames self, and negative appraisals) and activity participation (i.e., frequency of engaging in social and recreational activities) were used to predict depressive symptoms, PA and NA. Results indicated that while helplessness, blaming oneself, negative appraisals, and activity participation all significantly predicted depressive symptoms, only negative cognitive variables significantly predicted NA, and only activity participation significantly predicted PA. These data confirm that depressive experience consists of two relatively independent components - increased Negative Affect and reduced Positive Affect - which have unique correlates in negative cognitions and activity participation. If confirmed, the findings suggest the utility of focusing interventions on each of these components in the management of depressive symptoms.
