High-fidelity perceptual long-term memory revisited--and confirmed

Experiments on short-term perceptual memory for elemental visual attributes, such as contrast, motion, orientation, and spatial frequency, have relied on a delayed discrimination technique in which the subject compares two stimuli presented at different points in time and memory is indexed by discrimination thresholds measured for the different time intervals between reference and test. In a variant of this procedure, used in experiments on long-term memory, the presentation of a single reference is followed by a memory test that combines two-alternative forced-choice decisions with the method of constant stimuli. With this procedure, it is impossible to distinguish the effects of criterion-setting processes and memory on performance, but this confound can be eliminated by testing many subjects and having each subject make a single decision. The resulting "group thresholds" are stable across time intervals of 24 hr, confirming previous findings of high-fidelity storage in the long-term memory range.     

How evolutionary theory faces the reality

The paper sketches an account of explanatory practice in which explanations are viewed as answers to explanation-requiring questions. To avoid difficulties in previous proposals, the paper uses the structuralist account of theory structure, arguing that theories are complex and evolving entities formed around a conceptual core and a set of intended applications. The argument is that this view does better justice to theories which involve a number of different kinds of theory-elements to give narrative explanations. Theories are, among other things, devices which can be used to turn explanation-requiring questions into a form which allows assessment of potential answers. Evolutionary theory, both in Darwin's and the modern synthetic forms, are used as examples. The view advanced is that modern evolutionary theory need not have a unique core to which other theories serve as subcontractors.     

The distribution of infant attention during object examination

The distribution of attention during toy play was studied in 6‐, 9‐ and 12‐month‐old infants. Heart rate and behavior measures of attention were collected as the infants interacted with objects. There was a large deceleration of heart rate at the beginning of behaviorally defined focused attention, but little heart rate change for looks that only had behaviorally defined casual attention. Heart‐rate‐defined sustained attention occurred more frequently at the transition from the first instance of casual attention within a look to focused attention and during the cycling between subsequent epochs of casual and focused attention. These results show that heart rate and behavioral measures of attention are closely related in young infants at the beginning and end of object interaction but are inconsistently related within a single look at an object.     

Bilingualism Is Associated with a Delayed Onset of Dementia but Not with a Lower Risk of Developing it: a Systematic Review with Meta-Analyses

Neuropsychology Review - Some studies have linked bilingualism with a later onset of dementia, Alzheimer’s disease (AD), and mild cognitive impairment (MCI). Not all studies have observed...     

Counsellors' experiences of working with suicidal clients: An exploratory study

Counselling is increasingly available in a wide variety of contexts, including mental health and psychiatric services. As a consequence, counsellors increasingly work with clients who present with suicidal ideation, expressing either suicidal thought and/or intent in the counselling session. This paper describes an exploratory study that examined the experience of counsellors when working with suicidal clients. The paper considers counsellors' behavioural, cognitive and emotional responses to such suicidal expression, both on a personal and professional level. The research employed semi‐structured interviews. A constant comparative method was used in analysing the transcribed interview text. Results suggest that counsellors experience a range of responses when their clients express suicidal thought, including fear, anxiety, anger and professional impotence. The interviewees also expressed self‐doubts about their professional competence. In addition, they identified the threat of litigation for negligent practice and the lack of confidence in appropriate risk assessment approaches as significant causes for concern. The implications for further research, and practice, are discussed.     

Trends and Progress in Philosophy

This article is in three parts. The first discusses trends in philosophy. The second defends reliance on intuitions in philosophy from some doubts that have recently been raised. The third discusses Philip Kitcher's contention that contemporary analytic philosophy does not have its priorities straight. While the three parts are independent, there is a common theme. Each part defends what is regarded as orthodoxy from attacks. Of course there are other reasonable challenges to philosophical methodology. The article's aim is just to respond to some charges that have been made.     

Counsellors' perceptions of client progression when working with clients who intentionally self‐harm and the impact such work has on the therapist

Introduction: This paper describes a qualitative study focusing on counsellors' perceptions of client progression when working with clients who intentionally self‐harm and the impact this has on the therapist. Method: Semi‐structured interviews were employed and the constant comparative method utilised to analyse the data. Findings: Findings indicate that counsellors experience intense emotions in response to self‐harm including: shock; sadness; anxiety; anger; and frustration. Counsellors also struggled to manage the tension between multiple dualities, corresponding to professional opinions of a seemingly polar opposite nature. Although participants indicated a requirement to work in a client‐led way, they all had either an explicit or implicit agenda for change. These two conflicting states create a tension for a counsellor that is difficult to resolve. In addition there were various views of client progression, yet all participants agreed that progression was not simply about stopping self‐harm. Conclusion: There is a significant impact on the counsellor when working with clients who intentionally self‐harm and the complexity of the phenomenon appears to exacerbate their anxiety. Implications: Further research within the counselling field focusing on the ambiguous nature of the subject may increase understanding, which in turn may contribute to greater therapist efficacy when working with this client group.
