William Healy (1869-1963): pioneer child psychiatrist and criminologist

William Healy, M.D., a pioneer psychiatrist and criminologist, established the first child guidance clinic in the United States in 1909, and was an early advocate of both the "team approach" and the "child's own story" in treatment and research. One of the founders and the first president of the American Orthopsychiatric Association, Healy helped introduce Freudian thought into the United States. Among his contributions to the field of criminology are his book The Individual Delinquent (1915) and his "multifactor theory" of delinquency, which broadened the field and moved it away from European criminology's stress on genetic factors. Healy developed an elaborate methodology for the complete study of the offender by a variety of specialists. He was also a reformer in the field of corrections, based on his investigations of several institutions for delinquents.     

Naming times for the Snodgrass and Vanderwart pictures

This paper reports the results of two experiments. In the first, voice-key naming times were collected and in the second, keypress naming times were collected for 250 of the Snodgrass and Vanderwart (1980) pictures. The resulting naming times and correct naming rates were well predicted in multiple regression analyses by one or another measure of codability (name or concept agreement) and by age-of-acquisition ratings collected specifically for this study. Voice-key responses appeared to be somewhat more sensitive indicators of naming difficulty, although keypress responses did remarkably well. The Appendix presents the age-of-acquisition ratings, the trimmed vocal and keypress naming times, and the correct naming rates from the two experiments for the 250 pictures.     

Police evaluation research: an experimental and cost-benefit analysis of a helicopter patrol in a high crime area

The significance of a helicopter patrol procedure directed toward prevention of home burglaries was evaluated from experimental and cost-benefit perspectives. The helicopter patrolled one city zone from 9 a.m. to 5 p.m. for two 12-day periods. Each 12-day period was separated by a baseline period in which only normal patrol-car levels were maintained. Significantly reduced burglary levels during the intervention periods, compared to baseline periods, documented the experimental significance of the helicopter procedure. The cash costs of implementing the patrol procedure were compared to two estimates of the resulting cash benefits. This latter cost-benefit analysis was supplemented by a discussion of the intangible costs and benefits of the helicopter procedure. Taken together, these analyses documented that the marginal costs of the helicopter intervention were exceeded by all estimates of benefits.     

Disambiguating conscious and unconscious influences: do exclusion paradigms demonstrate unconscious perception?

Does exclusion failure--responding with previously presented words despite instructions to avoid doing so--demonstrate unconscious influences? This article examines exclusion-based evidence for unconscious perception. I propose an alternative signal detection theory (SDT) framework that can account for exclusion failure and ostensibly convergent qualitative differences without positing additional unconscious perceptual mechanisms. In the proposed SDT model, exclusion failure is a criterion artifact, similar to classic SDT-based critiques of subjective threshold approaches. However, it is suggested that exclusion approaches do demonstrate that response strategies are applied only to above-criterion stimuli and thereby illustrate important qualitative differences between two conscious processes: phenomenal awareness itself and higher-order (i.e., metacognitive) decision processes.     

Conceptual versus Perceptual Priming in Incomplete Picture Identification

This paper examined conceptual versus perceptual priming in identification of incomplete pictures by using a short-term priming paradigm, in which information that may be useful in identifying a fragmented target is presented just prior to the target’s presentation. The target was a picture that slowly and continuously became complete and the participants were required to press a key as soon as they knew what it was. Each target was preceded by a visual prime. The nature of this prime varied from very conceptual (e.g., the name of the picture’s category) to very perceptual (e.g., a similar-shaped pictorial prime from a different category). Primes also included those that combined perceptual and conceptual information (e.g., names or images of the target picture). Across three experiments, conceptual primes were effective while the purely perceptual primes were not. Accordingly, we conclude that pictures in this type of task are identified primarily by conceptual processing, with perceptual processing contributing relatively little.     

Spirituality in Older Adulthood: Existential Meaning,Productivity, and Life Events

The purpose of this article is to explore the relationship of spirituality and older adulthood, especially focusing on factors that may result in an increased spirituality among the elderly. Older adulthood, as the accumulation of insight gleaned from difficult lessons learned through life, offers the opportunity to embrace human finitude, to recognize life’s continuity and to grow in clarity about God and God’s presence. Wisdom gained through the experiences of vulnerability and transition serves as a resource to self and others. This article draws on the reflections of William M. Clements, Ph.D., Edna and Lowell Craig Professor of Pastoral Care and Counseling at the Claremont School of Theology.     

A Developmental Trajectory in Implicit Memory is Revealed by Picture Fragment Completion

Dissociations between performance on implicit and explicit tasks have often been taken as evidence that different neural structures subserve the two types of memory. One such dissociation involves developmental differences that emerge in explicit tasks, but which appear to be absent in implicit tasks. Such findings are consistent with the idea that implicit memory is subserved by a more primitive system that evolves earlier at both phylogenetic and ontogenetic levels. The present paper reviews previous studies that claimed to find evidence that implicit memory is fully developed in very young children. Issues of measurement error, ceiling effects, and insufficient power brought up questions about those studies with respect to the developmental issue. The present study compares performance on implicit (picture fragment completion) and explicit (free recall and recognition) memory tasks with groups ranging in age from 5–28 years. We find a reliable developmental trend in both implicit and explicit performance in which the former cannot be attributed to the operation ofexplicit memory processes. Thus, we conclude that implicit memory, like explicit memory, develops with age.     

The fate of originally presented surface information following recall errors in sentence memory tasks

Pictures are remembered better than their names. This picture superiority effect in episodic memory has been attributed either to the greater sensory distinctiveness of pictures or to their greater conceptual distinctiveness. Weldon and Coyote (1996) tested the conceptual distinctiveness hypothesis by comparing how well pictures as opposed to words primed in two conceptual implicit memory tasks (category production and word association). They found no picture superiority in priming and concluded that the basis of the picture superiority effect must then be pictures' greater sensory distinctiveness. Using the same logic, we compared how well pictures as opposed to words primed in a perceptual implicit memory task (picture and word fragment identification). The sensory distinctiveness theory would predict that pictures should prime picture fragment identification better than words prime word fragment identification, a result we call the picture superiority in within-form priming. Across three experiments which manipulated the encoding task at study, only one showed picture superiority in within-form priming. In contrast, in all three experiments there was robust picture superiority in recall, and exposure to pictures and words at study and test produced independent effects in which both study and test exposure to pictures was more effective for recall than exposure to words. We consider how these results might be reconciled by differences in retrieval demands between recall and fragment identification.     

Automatic measurement of propositional idea density from part-of-speech tagging

The Computerized Propositional Idea Density Rater (CPIDR, pronounced "spider") is a computer program that determines the propositional idea density (P-density) of an English text automatically on the basis of part-of-speech tags. The key idea is that propositions correspond roughly to verbs, adjectives, adverbs, prepositions, and conjunctions. After tagging the parts of speech using MontyLingua (Liu, 2004), CPIDR applies numerous rules to adjust the count, such as combining auxiliary verbs with the main verb. A "speech mode" is provided in which CPIDR rejects repetitions and a wider range of fillers. CPIDR is a user-friendly Windows .NET application distributed as open-source freeware under GPL. Tested against human raters, it agrees with the consensus of two human raters better than the team of five raters agree with each other [r(80) = .97 vs. r(10) = .82, respectively].
