A semantics-based approach to the "no negative evidence" problem

Previous studies have shown that children retreat from argument-structure overgeneralization errors (e.g., * Don't giggle me ) by inferring that frequently encountered verbs are unlikely to be grammatical in unattested constructions, and by making use of syntax-semantics correspondences (e.g., verbs denoting internally caused actions such as giggling cannot normally be used causatively). The present study tested a new account based on a unitary learning mechanism that combines both of these processes. Seventy-two participants (ages 5–6, 9–10, and adults) rated overgeneralization errors with higher (* The funny man's joke giggled Bart ) and lower (* The funny man giggled Bart ) degrees of direct external causation. The errors with more-direct causation were rated as less unacceptable than those with less-direct causation. This finding is consistent with the new account, under which children acquire—in an incremental and probabilistic fashion—the meaning of particular constructions (e.g., transitive causative = direct external causation) and particular verbs, rejecting generalizations where the incompatibility between the two is too great.     

Realizing complex delayed intentions in young and old adults: The role of planning aids

Although it has been suggested that the delayed realization of intended actions should benefit from appropriate intention planning, empirical evidence on this issue is scarce. In three experiments, we examined whether and which planning aids provided in the intention formation phase affect delayed intention realization in young and old adults. One finding was that intention planning directly affected delayed intention realization: instructing participants to include the cue for appropriate intention initiation in their plans benefited delayed performance. Another finding was that older adults' performance was improved when they were guided in structuring their plan in combination with guidance in implementing this plan after a delay. In sum, the results point to the importance of plan-related factors for understanding the delayed realization of intended actions.     

Suppression effects on musical and verbal memory

Three experiments contrasted the effects of articulatory suppression on recognition memory for musical and verbal sequences. In Experiment 1, a standard/comparison task was employed, with digit or note sequences presented visually or auditorily while participants remained silent or produced intermittent verbal suppression (saying "the") or musical suppression (singing "la"). Both suppression types decreased performance by equivalent amounts, as compared with no suppression. Recognition accuracy was lower during suppression for visually presented digits than during that for auditorily presented digits (consistent with phonological loop predictions), whereas accuracy was equivalent for visually presented notes and auditory tones. When visual interference filled the retention interval in Experiment 2, performance with visually presented notes but not digits was impaired. Experiment 3 forced participants to translate visually presented music sequences by presenting comparison sequences auditorily. Suppression effects for visually presented music resembled those for digits only when the recognition task required sensory translation of cues.     

Forced Migration among Latinx Children and their Families: Introducing Trilateral Migration Trauma as a Concept to Reflect a Forced Migratory Experience

ABSTRACT

Forced migration is a process where people must leave their countries of origin due to situations of war, human rights violations, torture, and political reasons, among other factors. This article presents a working definition of forced migration with a focus on the experience of Latinx children and their families. Venezuela and the Northern Triangle of Central America are presented as regional examples and highlight the state of crisis regarding migration in Latin America. The author introduces the concept of trilateral migration trauma as a new model to understand forced migration experiences. Mental health considerations faced by children who forcibly migrate from their homelands are considered. The “push-pull” theory of migration is critiqued in the context of a forced migratory experience.     

Behavioral competition in a case of Rett syndrome

Major behavioral features of Rett syndrome are the loss of instrumental reaching and grasping and the presentation of some variant of hand-hand or hand-mouth stereotypy. As part of an experimental home intervention program, a 3-year-old girl with Rett syndrome was exposed to four types of contingency games designed to elicit instrumental reaching, kicking, vocalization, and eye movement, respectively. Parent and subject performance were videorecorded on seven occasions over the initial 2-month period. Evaluation of these records provided evidence of contingency learning in all but the vocalization games. Stereotypic hand clasping was examined in relation to the performance of instrumental behavior (reaching, kicking, looking). Coincidental (short-term mutual inhibition arising by chance co-occurrence), associative (short-term mutual inhibition arising by having elicitor in common), and foundational (long-term mutual inhibition arising by having neural network in common) forms of specific behavioral competition were defined and examined. Evidence for coincidental and foundational competition was found in the relation between reaching and hand clasping. Implications for the support of functional hand use are discussed.     

Teaching ethics in engineering and computer science: A panel discussion

At a conference, two engineering professors and a philosophy professor discussed the teaching of ethics in engineering and computer science. The panelists considered the integration of material on ethics into technical courses, the role of ethical theory in teaching applied ethics, the relationship between cases and codes of ethics, the enlisting of support of engineering faculty, the background needed to teach ethics, and the assessment of student outcomes. Several audience members contributed comments, particularly on teaching ethical theory and on student assessment. This panel discussion took place at a mini-conference, Practicing and Teaching Ethics in Engineering and Computing, held during the Sixth Annual Meeting of the Association for Practical and Professional Ethics, Washington, D.C., March 8–9, 1997. Biographical information on panelists: Charles Glagola is an assistant professor of civil engineering at the University of Florida. He is a registered professional engineer in the states of Florida and Alabama. Before coming to academia, he had extensive industry experience culminating with his owning and operating a construction and engineering firm in Pensacola, Florida. He currently teaches engineering ethics as part of a professional issues course in the Department of Civil Engineering, and a one-hour engineering ethics course that is offered to all engineering students through the College of Engineering. Moshe Kam is professor of electrical and computer engineering at Drexel University. He heads Drexel’s Data Fusion Laboratory which specializes in multisensor systems and robot navigation. His professional interests include detection and estimation, distributed decision making, forensic applications of image processing, and engineering ethics. Michael Loui is professor of electrical and computer engineering and associate dean of the Graduate College at the University of Illinois at Urbana-Champaign. From 1990 to 1991, he served at the National Science Foundation in Washington, D.C. His scholarly interests include computational complexity theory, theory of parallel and distributed computation, fault-tolerant software, and professional ethics. Caroline Whitbeck is a philosopher of science, technology and medicine and is the Elmer G. Beamer-Hubert H. Shneider Professor in Ethics at Case-Western Reserve University. She also directs the WWW Ethics Center for Engineering & Science— http://ethics.cwru.edu— under a grant from the National Science Foundation. The focus of her current work is practical ethics, especially ethics in scholarly and scientific research. Her book, Ethics in Engineering Practice and Research, will appear from Cambridge University Press in winter 1997–98.     

Childhood abuse and spiritual development among women religious

Childhood abuse is known to have a negative influence on human development. This study expected to find a spiritual attitude of acceptance, as measured by the Ego Grasping Orientation scale, would help mitigate effects of childhood abuse in the realm of spiritual development. Spiritual Experience Index (SEI) scores for 350 religious women were treated as a measure of spiritual maturity. Contrary to expectation, however, the sexually and the physically abused groups with a more accepting attitude scored lower on the SEI than the abused with a more controlling attitude and the nonabused. Implications for spiritual development and well-being are discussed.     

PREDICTORS OF RESPONSES TO UNWANTED SEXUAL ATTENTION

Data were collected from 4,011 male and female university students, faculty, and staff regarding responses to unwanted sexual attention. Women and undergraduate students reported the highest incidence of unwanted sexual attention; most harassers were peers. Ignoring the behavior was the most common response, followed by avoiding the harasser and talking to others about the harassment. Harassment severity was the strongest predictor of responses, with more direct responses being made to more severe harassment. Bivariate correlational analyses suggested that unwanted sexual attention was rated as more distressing by women than by men, by faculty/staff than by students, by individuals with less tolerant attitudes toward harassment, and when the harasser was in a position of authority or when the harassment was of longer duration. In path analyses, only the relations between attitudes and responses were mediated by differences in perceived severity. The gender and status (i.e., student vs. faculty/staff) of the harassee, the duration of the harassment, and whether the harasser was in a position of authority had direct effects on responses not attributable to perceived severity. Implications for policy and future research are discussed.
