复述、提取抑制与有意遗忘的实验研究

有意遗忘是关于记忆研究的另一种实验范式,对于在实验中出现的要求遗忘的学习项目的记忆成绩差于要求记忆的项目的结果,目前主人存在着两种理论解释：基于编码的理论和基于提取抑制的理论。该实验运用单字提示方式,采用控制较为严密的补笔测验方法和加入所谓的“无关项”,对有意遗忘的心理过程进行进一步的探讨,实验表明：在单了提示方式下,被试在进行有意遗忘的过程中,既对记忆项进行了有意的复述又对遗忘项产生了提取抑制。     

Encouraging Occupation: A Systematic Review of the Use of Life Review and Reminiscence Therapy for the Treatment of Depressive Symptoms in Older Adults

The present systematic review investigates the efficacy of both life review and reminiscence therapy interventions in the treatment of depressive symptoms in older adults. A systematic review of the literature was conducted using three databases: Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, and PsycINFO. Six studies met the inclusion criteria, and pertinent variables were extracted for data analysis. In all six articles, the reminiscence therapy or life review intervention was found to be effective in the treatment of depressive symptoms in older adults. These interventions are appropriate for use in occupational therapy practice, as occupational therapists are well-equipped to treat the psychosocial needs of individuals.     

Evolutionary Pluralism: A New System of Systems Philosophy

When Darwin wrote his ‘On the origin of species…” (1859) he focused on evolution as a property of living organisms in interaction with abiotic and biotic elements in the world. This viewpoint is still dominant amongst biologists. For particle physicists and cosmologists evolution refers to a larger scale, ranging from quarks and atoms to galaxies, stars and planets (i.e. Pagels 1985, Hawking 1988). To close the gap between such different viewpoints, a wide range of perspectives on an interdisciplinary understanding of system development has been published (i.e. Teilhard de Chardin 1966, von Bertalanffy 1968, Varela 1979, Prigogine and Stengers 1984, Laszlo 1996). As an integrative concept, the construction of nature from a hierarchy of system layers forms a central tenet in general system research and the stepwise construction of this layered hierarchy can be regarded as an interdisciplinary evolution theory. Surprisingly, the literature offers no unequivocal rules to recognise a multilayer hierarchy in nature. This presents an obstacle for interdisciplinary approaches to evolution.

Searching a solution to part of the above hierarchy problem, the present paper is dedicated to the analysis of a special kind of layering in natural systems, which is based on transitions between ‘building block’ systems. To identify these building blocks, and the transitions from building block x at level A, to building block y at level B, the focus of this study is further limited to ‘hypercydic dynamics’ and ‘containment’. On the basis of these criteria, a hierarchy is created which shows no possibilities for ‘bypasses’. It connects hadrons to atoms, atoms to cells, and cells to neural networks. Implications of this hierarchy for system studies and evolution are discussed.     

Treatment of Panic Disorder with Agoraphobia: Randomized Placebo‐Controlled Trial of Four Psychosocial Treatments Combined with Imipramine or Placebo

Few randomized controlled trials have included panic disorder patients with moderate to severe agoraphobia. Therefore, this population was studied using pharmacotherapy as well as psychotherapy. At the time of the study, imipramine was widely used as a pharmacological treatment. Also, current practice guidelines for patients with panic disorder find selective serotonin reuptake inhibitors and tricyclic antidepressants roughly comparable in terms of efficacy. Therefore, the main objective of this study is to compare four psychosocial treatments—cognitive and graded in vivo exposure treatments, graded in vivo exposure, cognitive treatment, and supportive therapy—to evaluate the benefits of combining cognitive therapy with exposure in vivo. These treatments were combined with imipramine or placebo for a total of eight experimental conditions. Participants presented moderate to severe agoraphobia. The method involved a randomized, double‐blind, placebo‐controlled trial with 137 participants who completed a 14‐session protocol involving the treatments just mentioned. Measures were taken at baseline and posttreatment and at 3‐, 6‐, and 12‐month follow‐up. All treatment conditions were statistically and clinically effective in reducing self‐reported panic–agoraphobia symptoms over the 1‐year follow‐up. No statistical differences were observed between imipramine and placebo conditions. This study found that all treatment modalities helped reduce panic and agoraphobic symptomatology over a 1‐year follow‐up period. These surprising results support the need to document the relations among the various components of an intervention. This would make it possible to assess the relative efficacy of the treatment components rather than of the intervention as a whole.     

A Study of Happiness and Unhappiness in the Childhood and Adolescence of Girls in Different Cultures

Experiments were reviewed which dealt with the effect of an auditory cue stimulus on sensitivity to a visual detection stimulus, and vice versa. In most cases the heteromodal cue was temporally varied around the time of occurrence of the detection stimulus.

Different results were reported when a prolonged cue was used (which overlapped the detection stimulus when the onsets of both were not simultaneous) than when a brief-duration cue was used: e.g., in the former case, but not in the latter, sensitivity to the detection stimulus was affected by the intensity of a clearly perceptible heteromodal cue. Es tended to explain the effects of prolonged cue in “neurophysiological-interaction” terms and of brief-duration cue in “attentional” terms. Delta t (difference between times of detection-stimulus and cue onset) was most likely to affect sensitivity to the detection stimulus when marker stimuli reliably informed S when to attend for the detection stimulus, but did not exactly define its time of possible occurrence. A consistent delta-t effect was that a light-cued sound stimulus was best detected when the flash preceded it by 0 to 500 msec.     

Meaning in life across the life span: Levels and correlates of meaning in life from emerging adulthood to older adulthood

Meaning in life is thought to be important to well-being throughout the human life span. We assessed the structure, levels, and correlates of the presence of meaning in life, and the search for meaning, within four life stage groups: emerging adulthood, young adulthood, middle-age adulthood, and older adulthood. Results from a sample of Internet users (N = 8756) demonstrated the structural invariance of the meaning measure used across life stages. Those at later life stages generally reported a greater presence of meaning in their lives, whereas those at earlier life stages reported higher levels of searching for meaning. Correlations revealed that the presence of meaning has similar relations to well-being across life stages, whereas searching for meaning is more strongly associated with well-being deficits at later life stages.     

Childhood Maltreatment,Adult Attachment,and Depression as Predictors of Parental Self-Efficacy in At-Risk Mothers

Childhood abuse and neglect can have far-reaching effects on adult relationships, mental health, and parenting. This study examined relations between maltreatment types, anxious and avoidant adult attachment, maternal depression, and parental self-efficacy in a community sample of 76 at-risk mothers. After controlling for other forms of maltreatment, emotional abuse uniquely predicted higher levels of anxious attachment and maternal depression. Structural equation modeling revealed that childhood maltreatment predicted lower parental self-efficacy through indirect pathways involving anxious attachment and depression. Specifically, maltreatment's influence on maternal depression was mediated by attachment anxiety, while its influence on parental self-efficacy was mediated by depressive symptoms. Results are discussed in terms of attachment theory and ways in which parental self-efficacy contributes to adaptive caregiving behavior.     

Anticipatory Anxiety of an Imminent Economic Collapse

This article describes a prospective study of 1,200 participants, half of whom were offspring of trauma survivors, and their emotional symptom levels before and after the Corralito, an economic crisis that occurred in Argentina at the end of 2001. The authors report pre- and postcrisis data on anxiety and depression in a group of adult offspring of victims of the Dirty War (1976–1983) in an attempt to ascertain whether they are at greater risk than a control group for developing anxiety and depression in response to an economic crisis. The results indicated the offspring of war victims experienced greater emotional distress than the control subjects before, but not after the imposition of the Corralito.     

Comprehension of Sexual Consent as a Key Factor in the Perpetration of Sexual Aggression Among College Men

The comprehension of sexual consent is a crucial factor in healthy sexual relationships. This study examined the connection between the understanding of sexual consent and perpetration of sexual aggression. We surveyed 217 heterosexual male college students (M age = 20.9 years) using measures of sexual aggression, comprehension of sexual consent, rape myth acceptance, conformity to masculine norms, peer support of abuse, and attachment to abusive peers. We tested models examining factors related to comprehension of consent and the extent to which comprehension of consent was related to perpetration of sexual aggression. Rape myth acceptance, peer support of abuse, and conformity to masculine norms were found to predict comprehension of consent, which mediated the relationship between the social and cognitive variables and sexual aggression.     

The role of executive function in autobiographical memory retrieval: does the type of cue word matter?

ABSTRACT

Autobiographical memories are memories for personally experienced life events. Previous research has revealed individual differences in the ability to recall specific memories that happened at a particular time and place. Some studies suggest such differences can be attributed to the varying capacity of executive function. However, little is known regarding which specific executive function skills predict autobiographical memory specificity. Participants were asked to complete multiple measures of executive function as well as an autobiographical memory task in which they were asked to recall a specific personal memory connected to concrete and abstract cue words. We hypothesised that executive function will be positively related to autobiographical memory specificity and that this relation will be moderated by the cue word type. The results revealed that individuals with higher executive function skills, specifically, higher inhibitory control and cognitive flexibility, recalled significantly more specific memories than those with lower executive function skills; however, no significant interaction between executive function ability and cue word type was found.
