Relational and imageric recall in young and older adults under conditions of high task demand

Research indicates the presence of an age-related pictorial processing deficit, for which the elderly may attempt to compensate through the use of relational information. Cognitive asynchrony theory, a recent synthetic formulation which unites elements of the generalized slowing hypothesis, environmental support theory, and the item-specific/relational information distinction, has proven useful in a number of experiments in explaining these aspects of visual cognitive aging. The present experiments tested this theoretical formulation under high processing demand conditions in both the relational and the pictorial/item-specific realm. Young and older adults yielded a complex pattern of results consistent with the cognitive asynchrony synthesis of these theoretical considerations. The present experiments add to the growing body of findings indicating that the cognitive subsystems of memory decline at different rates, that the differences in cognitive processing between young and older adults tend to be more quantitative than qualitative, and that the global age-related memory deficits of popular belief are in fact relatively circumscribed and specific.

The Development and Validation of Brief and Ultrabrief Measures of Values

Values are a central personality construct and the importance of studying them has been well established. To encourage researchers to integrate measures of values into their studies, brief and ultrabrief instruments were developed to recapture the 10 values measured by the 40-item Portrait Values Questionnaire (PVQ; Schwartz, 2003 Schwartz, S. H. (2003). A proposal for measuring value orientations across nations. In Questionnaire development report of the European Social Survey (pp. 259–319). Retrieved from http://www.europeansocialsurvey.org/index.php?option=com_docman&;task=doc_view&;gid=126&;Itemid=80 [Google Scholar]). Rigorous psychometric procedures based on separate derivation (N = 38,049) and evaluation (N = 29,143) samples yielded 10- and 20-item measures of values, which proved to be successful at capturing the patterns and magnitude of correlations associated with the original PVQ. These instruments should be useful to researchers who would like to incorporate a values scale into their study but do not have the space to administer a longer measure.     

Cognition at risk: Gestalt/feature-intensive processing, attention deficit, and substance abuse

Attention deficit hyperactive disorder (ADHD) is associated with elevated levels of substance abuse, but the cognitive linkages involved have been little explored. The present study builds upon earlier work showing that more gestalt, as opposed to feature-intensive, styles of processing are conductive to substance abuse, especially in those with ADHD symptoms. The work reported here indicates that a protective factor against substance abuse may lie in relatively efficient heuristic processing, especially synthetic or inferential heuristic processing, but further demonstrates that those with ADHD symptoms tend to have poorer abilities in this regard, even at the subclinical, nondiagnosed level. Results are discussed in terms of the gestalt/featureintensive processing theory of cognition.     

Counsellor-delivered HIV risk reduction intervention addresses safer sex barriers of people living with HIV in KwaZulu-Natal, South Africa

This study developed an HIV risk reduction intervention for people living with HIV (PLWH) obtaining care at primary healthcare clinics in KwaZulu-Natal, South Africa by (1) conducting elicitation research to understand the dynamics of risk behaviour among PLWH, (2) modifying an existing HIV risk reduction intervention based on research findings and (3) conducting a pilot study to evaluate feasibility, acceptability and fidelity of the modified intervention implemented by trained lay counsellors at a rural clinic in KwaZulu-Natal. A total of 61 healthcare providers and 77 HIV+ patients from four primary healthcare clinics participated in 14 focus groups and 20 individual interviews to identify informational, motivational and behavioural skills (IMB) factors contributing to PLWH's sexual risk behaviour. Elicitation research findings were incorporated into a revised version of Options for Health, an evidence-based risk reduction intervention for PLWH in clinical care. In a 5-day training, lay counsellors learned strategies to address IMB barriers to safer sex identified in elicitation research. The revised intervention, which was implemented by six counsellors with 39 patients, was feasible to implement, acceptable to patients and counsellors, and implemented with good fidelity. This study makes an important contribution towards development of a theory-based HIV risk reduction intervention for PLWH linking prevention with treatment in South Africa.     

The role of error‐correction procedures in the reinforcement of errors

In Study 1 three different error‐correction procedures and a trial‐and‐error procedure were implemented in a Japanese word/phrase receptive identification task. Training procedures differed in the specific type of error that evoked error‐correction feedback. Outcomes indicated that when the error‐correction consequence was contingent on incorrect responses, incorrect responses predominated initially. When this feedback consequence followed no response, non‐responding initially prevailed. Task mastery was achieved in fewer trials with error‐correction procedures than with the no prompt/trial‐and‐error. However, post‐mastery probes 1 week after mastery indicated retention was greater for participants in the trial‐and‐error training condition. These patterns indicated that the feedback prompt itself could be functioning as a positive reinforcer. Demonstration of this effect would have been more definitive had individual participants been exposed to each experimental condition, and the limited number of participants in the trial‐and‐error group weakened conclusions from Study 1. These outcomes necessitated procedural replication. The initial question remained unanswered: if feedback were delivered contingent on trainee request and not contingent on errors, how would this affect errors and retention? Study 2, with a prompt‐request (‘Show me’) answered this question. Copyright © 2006 John Wiley & Sons, Ltd.     

An Empiricist Conception of the Relation Between Metaphysics and Science

It is widely acknowledged that metaphysical assumptions, commitments and presuppositions play an important role in science. Yet according to the empiricist there is no place for metaphysics as traditionally understood in the scientific enterprise. In this paper I aim to take a first step towards reconciling these seemingly irreconcilable claims. In the first part of the paper I outline a conception of metaphysics and its relation to science that should be congenial to empiricists, motivated by van Fraassen’s work on ‘stances’. There has been a considerable about of recent work devoted to van Fraassen’s ‘stance’ view, but it has not on the whole been noticed that the view has the potential to motivate a general empiricist conception of the relation between science and metaphysics. In the second and third sections I discuss two examples from biology to illustrate this conception: metaphysical punctuationism, and its relation to and influence on the thesis of punctuated equilibrium; and dialectical biology as defended by Levins and Lewontin.

     

False memories in women with self-reported childhood sexual abuse: an empirical study

Although controversy exists about the validity of memories of childhood abuse, little is known about memory function in individuals reporting childhood abuse. This study assessed memories for previously presented words, including the capacity for false memory of critical lures not actually present in the word list, in 63 subjects, including abused women with posttraumatic stress disorder (PTSD), abused women without PTSD, and men and women without abuse or PTSD. Abused women with PTSD had a higher frequency of false recognition memory of critical lures (95%) than abused women without PTSD (78%), nonabused women without PTSD (79%), or nonabused men without PTSD (86%). PTSD women also showed poorer memory for studied words and increased insertions of non-studied words other than critical lures. These findings are consistent with a broad range of memory alterations in abused women with PTSD.     

Coping dimensions, life stress, and adolescent substance use: a latent growth analysis

The relation of seven coping dimensions to substance (tobacco, alcohol, marijuana) use was tested with a sample of 1,668 participants assessed at mean age 12.5 years and two yearly follow-ups. An associative latent-growth model showed one index of engagement (behavioral coping) to be inversely related to initial level of adolescent use and growth over time in peer use. Three indices of disengagement (anger coping, helpless coping, and hangout coping) were positively related to initial levels of peer use and adolescent use and to growth in adolescent use. Life stress was positively related to initial levels for peer use and adolescent use and to growth in adolescent use. Moderation tests indicated that effects of coping were significantly greater at higher level of stress; behavioral coping buffered the effects of disengagement. Effects of life stress were greater for girls than for boys. Results are discussed with reference to mechanisms of coping-substance use relationships.     

Dyadic Influence of Adverse Childhood Experiences: Counseling Implications for Mental and Relational Health

Adverse childhood experiences (ACEs) predict physical and mental health. We examined dyadic differences in intimate partner relationship health by ACE score among couples with low to moderate income enrolled in a relationship education program. Overall, we found a high prevalence of ACEs, disproportionate representation in the highest risk ACE group, and a significant effect between ACEs and indicators of mental and relational health. Implications for counselors include support for an ACE‐informed approach to couples counseling services, as well as a holistic and systemic view of mental and relational health.     

The development of bodily self‐consciousness: changing responses to the Full Body Illusion in childhood

The present work investigates the development of bodily self‐consciousness and its relation to multisensory bodily information, by measuring for the first time the development of responses to the full body illusion in childhood. We tested three age groups of children: 6‐ to 7‐year‐olds (n = 28); 8‐ to 9‐year‐olds (n = 21); 10‐ to 11‐year‐olds (n = 19), and a group of adults (n = 31). Each participant wore a head‐mounted display (HMD) which displayed a view from a video camera positioned 2 metres behind their own back. Thus, they could view a virtual body from behind. We manipulated visuo‐tactile synchrony by showing the participants a view of their virtual back being stroked with a stick at the same time and same place as their real back (synchronous condition), or at different times and places (asynchronous condition). After each period of stroking, we measured three aspects of bodily self‐consciousness: drift in perceived self‐location, self‐identification with the virtual body, and touch referral to the virtual body. Results show that self‐identification with the virtual body was significantly stronger in the synchronous condition than in the asynchronous condition even in the youngest group tested; however, the size of this effect increased with age. Touch referral to the virtual body was greater in the synchronous condition than in the asynchronous condition only for 10‐ to 11‐year‐olds and adults. Drift in perceived self‐location was greater in the synchronous condition than in the asynchronous condition only for adults. Thus, the youngest age tested can self‐identify with a virtual body, but the links between multisensory signals and bodily self‐consciousness develop significantly across childhood. This suggests a long period of development of the bodily self and exciting potential for the use of virtual reality technologies with children.
