The Contribution of Executive Skills to Reading Comprehension

Although word recognition deficits (WRD) are a known cause of reading comprehension deficits (RCD), other contributions to RCD, including executive function (EF), have not been fully explored. We examined the contribution of EF (working memory and planning), along with attention, decoding, fluency, and vocabulary to reading comprehension in 60 children (including 16 WRD and 10 RCD), ages 9–15 years. After controlling for commonly accepted contributors to reading comprehension (i.e., attention, decoding skills, fluency, and vocabulary), EF continued to make a significant contribution to reading comprehension but not to word recognition skills. These findings highlight the need for consideration of the role of EF in RCD.     

Visual similarity effects on masked priming

We investigated the role of the visual similarity of masked primes to targets in a lexical decision experiment. In the primes, some letters in the target (e.g., A in ABANDON) had either visually similar letters (e.g., H), dissimilar letters (D), visually similar digits (4), or dissimilar digits (6) substituted for them. The similarities of the digits and letters to the base letter were equated and verified in a two-alternative forced choice (2AFC) perceptual identification task. Using targets presented in lowercase (e.g., abandon) and primes presented in uppercase, visually similar digit primes (e.g., 484NDON) produced more priming than did visually dissimilar digit primes (676NDON), but little difference was found between the visually similar and dissimilar letter primes (HRHNDON vs. DWDNDON). These results were explained in terms of task-driven competition between the target letter and the visually similar letter.     

Identification of tone duration, line length, and letter position: an experimental approach to timing and working memory deficits in schizophrenia

Patients with schizophrenia display numerous cognitive deficits, including problems in working memory, time estimation, and absolute identification of stimuli. Research in these fields has traditionally been conducted independently. We examined these cognitive processes using tasks that are structurally similar and that yield rich error data. Relative to healthy control participants (n = 20), patients with schizophrenia (n = 20) were impaired on a duration identification task and a probed-recall memory task but not on a line-length identification task. These findings do not support the notion of a global impairment in absolute identification in schizophrenia. However, the authors suggest that some aspect of temporal information processing is indeed disturbed in schizophrenia.     

Riddles in serial murder: A synthesis

This article blends the conclusions of four former law enforcement personnel who have investigated and apprehended serial killers, with pertinent principles derived primarily from the field of psychoanalysis. The four—John Douglas, Roy Hazelwood, Robert Keppel, and Robert Ressler—have written extensively about their investigations of serial killers. In their writings, they have answered many questions about the personality development of serial killers while leaving other questions only partially answered. This article expands the answers to three fundamental questions: What is the origin of the dynamics of serial killing? Why is the aggressive drive so singularly powerful and persistent in serial killers? Why is it that serial killers often reveal their identities to the police? In answering these three riddles, the contributions of four emotional pillars in the personality of killers are emphasized. The pillars include emotional hunger, anxiety and aggression, eroticism, and conscience structure. At times, these pillars merge and drive murderous behavior but the pillars lack the integration needed for healthy personality development. This synthesis offers a fuller understanding of the psychodynamics involved in serial killings.     

Suicide Behavior

ABSTRACT: A survey of community attitudes and beliefs concerning suicidal behavior is reported, in which women from two suburbs differing widely in their rates of hospital treated self-poisoning and self-injury were interviewed. Sympathetic attitudes to suicidal behavior and to those who engage in it were significantly more prevalent in the low-risk area. Community beliefs regarding lethality, etiology, and ability to distinguish suicide and “attempted suicide” are reported, and the relationship of these beliefs to attitudes is discussed.
