Assessing indices of happiness and unhappiness in individuals with developmental disabilities: a review

The behavioral deficits of individuals with profound multiple disabilities (PMD) make it difficult to assess their satisfaction and quality of life. To address this problem, researchers have recently evaluated affective behavior (i.e., indices of happiness and unhappiness) to document the effects of therapeutic interventions and to assist with clinically relevant decisions. We review the recent literature on indices of happiness and unhappiness and discuss its major themes. In addition, potential concerns with this technology are discussed and clinical recommendations are provided. Copyright © 2007 John Wiley & Sons, Ltd.     

Performance costs when emotion tunes inappropriate cognitive abilities: implications for mental resources and behavior

Emotion tunes cognition, such that approach-motivated positive states promote verbal cognition, whereas withdrawal-motivated negative states promote spatial cognition (Gray, 2001). The current research examined whether self-control resources become depleted and influence subsequent behavior when emotion tunes an inappropriate cognitive tendency. In 2 experiments, either an approach-motivated positive state or a withdrawal-motivated negative state was induced, and then participants completed a verbal or a spatial working memory task creating conditions of emotion-cognition alignment (e.g., approach/verbal) or misalignment (e.g., approach/spatial). A control condition was also included. To examine behavioral costs due to depleted self-control resources, participants completed either a Stroop task (Stroop, 1935; Experiment 1) or a Black/White implicit association test (IAT; Greenwald, McGhee, & Schwartz, 1998; Experiment 2). Participants in the misalignment conditions performed worse on the Stroop task, and they were worse at controlling their implicit attitude biases on the IAT. Thus, when emotion tunes inappropriate cognitive tendencies for one's current environment, self-control resources become depleted, impairing behavioral control.     

You deplete me: The cognitive costs of colorblindness on ethnic minorities

This study examined how priming Whites with colorblind or multicultural approaches to diversity prior to an interracial interaction affects ethnic minorities' cognitive functioning. Although ethnic minorities did not explicitly know which prime their White partner received, ethnic minorities paired with Whites primed with colorblindness (vs. multiculturalism) showed poorer cognitive performance on the Stroop (1935) color-naming task following the interaction. Furthermore, Whites in interracial interactions primed with colorblindness exhibited more behavioral prejudice, which mediated ethnic minorities' decreased cognitive performance. These findings suggest that Whites' exposure to certain ideologies may affect the cognitive performance of the ethnic minorities they encounter.     

The effects of positive and negative pre-sleep stimuli on dream experiences

In this study, the emotional and physical content of dreams was examined with post-sleep reports. In the first phase of the study, 45 students were asked to keep a dream diary for a week. The next week, the students were asked to look at a picture with positive, neutral, or negative affect in the evening before going to bed and then to record their dreams the following morning. Results showed that the pictures produced corresponding affect in morning dream reports, though physical elements of dreams and pictorial stimuli were not related to affect.     

The neuropsychology of depression and its implications for cognitive therapy

The past few years have witnessed a growing interest in the specialty of neuropsychology as well as continued support for cognitive therapy of depression. The purpose of this paper is the examination of the neuropsychology of depression and its implications for A. T. Beck's cognitive theory and therapy of depression ([1963] Thinking and Depression: Idiosyncratic Content and Cognitive Distortions,Archives of General Psychiatry, Vol. 9, pp. 324–333; [1964] Thinking and Depression,Archives of General Psychiatry, Vol. 10, pp. 561–571; [1967]Depression: Clinical, Experimental, and Theoretical Aspects, New York: Harper & Row). Specifically, the neuropsychological and cognitive theory and therapy literatures related to depression are reviewed followed by an antegration of these areas. Neuropsychological evidence is presented that both supports cognitive theory and therapy of depression and helps explain why such therapy may prove ineffective in treating depression. Implications for clinical practice, including neuropsychological assessment of depressives, and potential future research directions are also provided.     

The effects of rumination and negative cognitive styles on depression: a mediation analysis

Research on cognitive models of depression has identified negative cognitive styles and rumination as risk factors for depression. The present study examined the hypothesis that rumination mediates the effect of negative cognitive styles on depression. Specifically, we evaluated the differential effects of two aspects of rumination, characterized by brooding and reflection, on the relationship between negative cognitive styles and level of depressive symptoms. A total of 115 college students and 38 patients suffering from depressive disorders completed a battery of questionnaires measuring levels of depressive symptoms, brooding, reflection, and negative cognitive styles. The results support the notion that there exist two distinct dimensions of rumination and that, of the two, it is brooding and not reflection that mediates the relationship between negative cognitive styles and depression and contributes to its negative outcomes.     

The effect of cognitive load and hyperarousal on negative intrusive memories

Clinical theories of post-traumatic stress suggest that encoding processes at the time of a trauma are critical in determining whether intrusive memories will develop. Potential mechanisms that might influence the development of intrusive memories were studied, as was objective memory performance. In an analogue design, 65 participants were randomised to three conditions (cognitive load, hyperventilation, and control), and then watched a film of traumatic content. Intrusive memories were recorded during the experimental phase and at 1-week follow-up. Support was found for the prediction that verbal cognitive load and hyperventilation would facilitate intrusion development immediately following exposure to the trauma film; however, this was not maintained at follow-up. Consistent with cognitive models of post-traumatic stress, thought suppression and the distress associated with intrusive experiences mediated the relationship between distress caused by the film and intrusions at 1-week follow-up. Objective memory testing indicated that the three experimental groups showed similar recall and recognition performance for the content of the film; however, relative to the control group, individuals in the cognitive load condition were significantly less able to place film scenes in the correct order.     

The phantom leaf effect and its implications for near-death and out-of-body experiences

The phantom leaf effect seen in Kirlian photography may help researchers better understand near-death and out-of-body experience. While the process responsible for the phantom leaf effect is unknown, variations of Rupert Sheldrake's morphogenetic field theory offer three explanations for this phenomenon. Each of these variations has different implications for near-death and out-of-body experiences.     

Imaging episodic memory: implications for cognitive theories and phenomena

Functional neuroimaging studies are beginning to identify neuroanatomical correlates of various cognitive functions. This paper presents results relevant to several theories and phenomena of episodic memory, including component processes of episodic retrieval, encoding specificity, inhibition, item versus source memory, encoding-retrieval overlap, and the picture-superiority effect. Overall, by revealing specific activation patterns, the results provide support for existing theoretical views and they add some unique information which may be important to consider in future attempts to develop cognitive theories of episodic memory.     

Healthy happiness: effects of happiness on physical health and the consequences for preventive health care

Is happiness good for your health? This common notion is tested in a synthetic analysis of 30 follow-up studies on happiness and longevity. It appears that happiness does not predict longevity in sick populations, but that it does predict longevity among healthy populations So, happiness does not cure illness but it does protect against becoming ill. The effect of happiness on longevity in healthy populations is remarkably strong. The size of the effect is comparable to that of smoking or not.If so, public health can also be promoted by policies that aim at greater happiness of a greater number. That can be done by strengthening individual life-abilities and by improving the livability of the social environment. Some policies are proposed. Both ways of promoting health through happiness require more research on conditions for happiness.     

The abilities of children with mental retardation to remember personal experiences: implications for testimony

Investigated the abilities of children with mental retardation to remember the details of a personally experienced event. A simulated health check was administered to 20 children with mental retardation and 40 normally developing children, half matched on mental age (MA) and half matched on chronological age (CA) with the children with mental retardation. The children's memory was assessed immediately after the health check and 6 weeks later. Overall, the children with mental retardation accurately recalled the health check features, provided detail, and resisted misleading questions about features that did not occur. The group with mental retardation performed similarly to the MA matches on virtually all of the memory variables. The children with mental retardation performed worse than the CA matches on most of the memory variables, although they were able to recall a similar number of features. The findings are discussed in terms of the ability of children with mental retardation to provide accurate testimony.     

Philosophical conceptions of the self: implications for cognitive science

Several recently developed philosophical approaches to the self promise to enhance the exchange of ideas between the philosophy of the mind and the other cognitive sciences. This review examines two important concepts of self: the 'minimal self', a self devoid of temporal extension, and the 'narrative self', which involves personal identity and continuity across time. The notion of a minimal self is first clarified by drawing a distinction between the sense of self-agency and the sense of self-ownership for actions. This distinction is then explored within the neurological domain with specific reference to schizophrenia, in which the sense of self-agency may be disrupted. The convergence between the philosophical debate and empirical study is extended in a discussion of more primitive aspects of self and how these relate to neonatal experience and robotics. The second concept of self, the narrative self, is discussed in the light of Gazzaniga's left-hemisphere 'interpreter' and episodic memory. Extensions of the idea of a narrative self that are consistent with neurological models are then considered. The review illustrates how the philosophical approach can inform cognitive science and suggests that a two-way collaboration may lead to a more fully developed account of the self.     

The developmental origins of cognitive vulnerability to depression: temperament, parenting, and negative life events in childhood as contributors to negative cognitive style

Cognitive models of depression have been well supported with adults, but the developmental origins of cognitive vulnerability are not well understood. The authors hypothesized that temperament, parenting, and negative life events in childhood would contribute to the development of cognitive style, with withdrawal negativity and negative parental feedback moderating the effects of negative life events to predict more depressogenic cognitive styles. These constructs were assessed in 289 children and their parents followed longitudinally from infancy to 5th grade; a subsample (n = 120) also participated in a behavioral task in which maternal feedback to child failure was observed. Results indicated that greater withdrawal negativity in interaction with negative life events was associated with more negative cognitive styles. Self-reported maternal anger expression and observed negative maternal feedback to child's failure significantly interacted with child's negative events to predict greater cognitive vulnerability. There was little evidence of paternal parenting predicting child negative cognitive style.     

负性情绪调节中认知重评和分心策略的作用:ERPs研究

采用事件相关电位技术,考察了认知重评和分心两种情绪调节策略对负性情绪体验和脑电活动的影响。结果发现,认知重评后被试的负性情绪体验强度和LPP波幅(300~1300ms)比简单注视条件下低;分心后被试的负性情绪体验强度比简单注视条件下低,但LPP波幅显示比简单注视条件下高。这说明认知重评和分心对负性情绪体验和脑电活动的影响不同,负性刺激再次呈现时认知重评优于分心策略的调节。该研究为认知重评和分心的比较研究提供了神经电生理学方面的证据。     

Reappraisal and mindfulness: A comparison of subjective effects and cognitive costs

The present study investigated the relative effects of mindfulness and reappraisal in reducing sad mood and whether trait mindfulness and habitual reappraisal moderated the effects. The study also compared the extent to which implementation of these strategies incurred cognitive resources. A total of 129 participants were randomly assigned to receiving training in mindfulness, reappraisal, or no training prior to undergoing an autobiographical sad mood induction. Results showed that mindfulness and reappraisal were superior to no training, and equivalent in their effects in lowering sad mood. Compared to mindfulness, reappraisal resulted in significantly higher interference scores on a subsequent Stroop test, reflecting greater depletion of cognitive resources. Higher trait mindfulness, but not habitual reappraisal, predicted greater reductions in sadness across conditions. The study suggests that although mindfulness and reappraisal are equally effective in down-regulating sad mood, they incur different levels of cognitive costs.     

Family interference with work and workplace cognitive failure: The mitigating role of recovery experiences

The first goal of this study was to test whether family interference with work (FIW) is positively related to increased workplace cognitive failure (WCF), which is defined as errors made at work that indicate lapses in memory (e.g., failing to recall work procedures), attention (e.g., not fully listening to instruction), and motor function (e.g., unintentionally pressing control switches on machines). The second goal was to determine whether recovery experiences (psychological detachment and relaxation) during free time on evenings and weekends can mitigate (weaken) the positive relationship between FIW and WCF. Results based on data collected from 118 water utility employees suggest that FIW is indeed related to more WCF, and that psychological detachment from work mitigates this positive relationship. It was relatively less evident that relaxation plays such a mitigating role.     

Child abuse and negative explicit and automatic self-associations: The cognitive scars of emotional maltreatment

Individuals reporting Childhood Abuse (CA) (i.e., emotional neglect, emotional-, physical- and sexual-abuse) are marked by increased explicit (i.e. self-reported) negative self-associations, and an increased risk to develop depression or anxiety disorders. Automatic self-associations might play an important role in the development and maintenance of affective disorders after exposure to CA, since automatic associations are assumed to be involved in uncontrolled (spontaneous) affective behavior. This study examined whether individuals reporting a history of CA show stronger automatic (and explicit) self-depression and/or self-anxiety associations than individuals who report no CA in a large cohort study (Netherlands Study of Depression and Anxiety (NESDA), n = 2981). The Implicit Association Test (IAT) was utilized to assess automatic self-depression and self-anxiety associations. We found that CA was associated with enhanced automatic (and explicit) self-depression and self-anxiety associations. Additionally, when compared to physical- and sexual-abuse, Childhood Emotional Maltreatment (CEM; emotional abuse and emotional neglect) had the strongest link with enhanced automatic (and explicit) self-depression and self-anxiety associations. In addition, automatic and explicit negative self-associations partially mediated the association between CEM and depressive or anxious symptomatology. Implications regarding the importance of CA, and CEM in particular will be discussed.     

Test context affects recollection and familiarity ratings: implications for measuring recognition experiences

The binary remember/know task requires participants to dichotomize their subjective recognition experiences into those with recollection and those only with familiarity. Many variables have produced dissociative effects on remember/know judgments. In contrast, having participants make independent recollection/familiarity ratings has consistently produced parallel effects, suggesting the dissociations may be artifacts of using binary judgments. Bodner and Lindsay (2003) reported a test-list context effect with binary judgments: Increased remembering but decreased knowing for a set of critical items tested with a set of less-memorable (vs. more-memorable) items. Here we report a parallel effect of test-list context on recollection and familiarity ratings, induced by a shift in response bias. We argue that independent ratings are preferable to binary judgments because they allow participants to directly report the co-occurrence of recollection and familiarity for each item. Implications for the measurement of self-reported recognition experiences, and for accounts of recognition memory, are discussed.     

The role of personality and learning experiences in social cognitive career theory

We sought to extend the empirical literature on Social Cognitive Career Theory (SCCT) by testing (a) the posited indirect effect of personality on interests through learning experiences and sociocognitive mechanisms, and (b) hypotheses that self-efficacy percepts and outcome expectations derive from corresponding career-relevant learning experiences. Participants (327 college students) completed a measure of the Big Five personality factors and measures of learning experiences, self-efficacy, outcome expectations, and interests corresponding to each of Holland’s (1997) six RIASEC themes. Results of path analyses indicated that personality’s relation to interests was mediated via learning experiences and sociocognitive mechanisms; however, the extent of that mediation varied considerably across the different personality-interest relations. Findings also indicated strong support, across Holland themes, for SCCT’s hypothesized relations of learning experiences to self-efficacy and outcome expectations; however, for five of the six Holland themes, the relation between learning experiences and outcome expectations was at least partially mediated through self-efficacy.
