The effect of orthographic structure and lexical meaning on “same-different” judgments

Pairs of high frequency English words, orthographically acceptable pseudo-words, and non-word letter strings were presented in a “same”-“different” task. The mean reaction times for “same” judgments were ordered; real words were faster than pseudo-words, and pseudo-words were faster than non-words. The RTs for the “different”, judgments showed no differences among the three types of words, except in the first two days of practice in a blocked presentation condition when the difference between the real words and non-words was marginally significant. These and other results suggest that “same” judgments are based upon a comparison process which efficiently uses higher order semantic and orthographic information in words, whereas “different” judgments are based upon comparison process which performs a self-terminating search of the graphemic information in words. The results were also discussed with reference to hierarchical models of word perception and reading.     

Treatment, subtype, and word type effects in dyslexic children''s response to remediation

Children diagnosed as accuracy-disabled or rate-disabled readers (Lovett, 1984a, 1986, 1987) were randomly assigned to one of three treatment conditions providing training in word recognition and decoding skills (DS), oral and written language (OWLS), or classroom survival skills (an alternative treatment control). The experimental treatment programs exerted a positive treatment effect on the word recognition performances of both groups, but treatment-specific changes in contextual reading and oral language skill were not observed. Pre- and post-treatment comparisons on an experimental word recognition task revealed a post-test advantage for DS-trained children of both subgroups. Accuracy-disabled readers demonstrated treatment-specific gains for both orthographically regular words (e.g., wade) and for exception words (e.g., broad), with their gains greater on exception words. Rate-disabled children demonstrated treatment-specific gains only for exception words, but exhibited these gains following both the DS and the OWLS treatments. Although both experimental treatment programs were associated with a positive outcome for the rate disabled subgroup, DS training was associated with relatively greater treatment gain. These data suggest that the critical variables underlying the effectiveness of the DS treatment include the specific lexical knowledge these disabled readers acquired, their greater reliance on an orthographic pattern procedure in word recognition, and/or the fact that newly acquired items were practiced to a point approximating automatization.     

Sex and achievement domain: Cognitive patterns of success and failure

Subjects (N=439) were asked to write an account of an achievement of failure, and to describe it in terms of locus of standards (internal-external), conceptual focus (process-impact), and initial expectations for success (or failure). Additionally, accounts were classified on the basis of achievement domain (personal, interpersonal, mastery). Analyses of variance [2 (sex)×3 (domain)] for each cognitive measure revealed few sex differences. However, cognitive responses did vary as a function of achievement domain. Main effects for domain were observed under success instructions for locus of control (p<.0002) and under failure instructions for locus of control (p<.05), conceptual focus (p<.05), and expectations (p<.06). Interaction effects of sex and achievement domain were observed on locus of standards for success (p<.0002) and initial expectations preceding failure (p<.025), indicating that women were more responsive to domain differences than were men. Discriminant analyses indicated that cognitions were more readily patterned in terms of achievement domain than sex. Elaboration and incorporation of the concept of domain in cognitive models of achievement is suggested.     

Children's attributions of intentions to an invisible agent

Children ages 3-9 years were informed that an invisible agent (Princess Alice) would help them play a forced-choice game by "telling them, somehow, when they chose the wrong box," whereas a matched control group of children were not given this supernatural prime. On 2 unexpected event trials, an experimenter triggered a simulated unexpected event (i.e., a light turning on/off; a picture falling), and children's behavioral response to these events (i.e., moving their hand to the opposite box) was coded. Results showed a significant Age GroupxExperimental Condition interaction; the only children to reliably alter their behavior in response to the unexpected events were the oldest children (M=7 years 4 months), who were primed with the invisible agent concept. For children's posttest verbal explanations, also, only these children saw the unexpected events as being referential and declarative (e.g., "Princess Alice did it because I chose the wrong box"). Together, these data suggest that children may not regularly begin to see communicative signs as embedded in unexpected events until they are around 7 years of age.     

Theoretical Purity Versus Theoretical Layering in Marriage and Family Therapy

There seem to be two competing streams of thought about the use of theory in the marriage and family therapy literature: theoretical purity versus integrationism. We examined influence of theoretical orientation on client experience in therapy. Level of academic training (masters' versus doctoral degree) was investigated as a possible confounding variable. Results suggest that therapists in private practice are less inclined to practice pure forms of therapy.     

Links between local language competence and peer relations among Swiss and immigrant children: the mediating role of social behavior

The primary aim of this investigation was to evaluate a model in which children's social behaviors, including prosocial behavior, setting limits, and social withdrawal, were hypothesized to mediate the links between local language competence (LLC) and peer acceptance and victimization. Longitudinal data were collected via teacher and peer reports on 541 (286 boys and 255 girls) immigrant and Swiss native 5-to-6 year-old kindergarteners. Results showed the immigrant children were less fluent in the local language compared to native Swiss classmates. Moreover, results from structural equation models, with bootstrap tests of indirect effects, indicated that social behaviors mediated the link between LLC and the quality of children's peer relationships. Implications of these findings for school professionals are discussed, such as the need to help immigrant children make a smoother transition to their host communities by providing additional language and social supports while children acculturate and acclimate to their new surroundings and peer group.     

The Effects of Age on Second Language Grammar and Speech Production

The current study examined the age of learning effect on second language (L2) acquisition. The research goals of the study were twofold: to test whether there is an independent age effect controlling for other potentially confounding variables, and to clarify the age effect across L2 grammar and speech production domains. The study included 118 Mandarin-speaking immigrants and 24 native English speakers. Grammar knowledge was assessed by a grammaticality judgment task, and speech production was measured by native English speaking raters’ ratings of participants’ foreign accents. Results from the study revealed that the age of learning effect was robust for both L2 domains even after controlling for the influences of other variables, such as length of residence and years of education in the United States. However, the age of learning variable had a stronger impact on speech production than on grammar. The current results support the framework of multiple critical/sensitive periods (Long in Int Rev Appl Linguist 43(4):287–317, 2005; Newport et al. in Language, brain and cognitive development: Essays in honor of Jacques Mehler. MIT Press, Cambridge, MA, 2001; Werker and Tees in Dev Psychobiol 46(3):233–251, 2005).     

Deciphering Subjective Trajectories for Life Satisfaction Using Self‐versus‐Normative Other Discrepancies,Self‐esteem and Hope

Drawing on temporal and social comparison perspectives, we examined sources of the widespread belief that life gets better and better over time by determining how young adults evaluate their past, present and anticipated future life satisfaction (LS) relative to beliefs about normative others. We assessed whether patterns of subjective LS trajectories based on self‐versus‐normative other discrepancies varied as a function of self‐esteem and whether such patterns were accounted for by hope, encompassing goal‐related cognitions and motivations. University participants (n = 394) completed measures of their own and normative others' past, present and anticipated future LS, as well as self‐esteem and hope scales. Results from latent growth curve analyses demonstrated that high‐self‐esteem and low‐self‐esteem individuals perceived normative others' LS as progressing on a similar upward subjective temporal trajectory; however, high‐self‐esteem individuals perceived self‐improvement from past to present LS and self‐consistency from present to future LS relative to others. Low‐self‐esteem individuals perceived self‐consistency from past to present LS and self‐improvement from present to future LS relative to others. These associations were accounted for by hope. This research highlights the utility of combining temporal and social comparison perspectives for understanding how people envision their LS unfolding over time.

Peak shift in honey bee olfactory learning

If animals are trained with two similar stimuli such that one is rewarding (S+) and one punishing (S?), then following training animals show a greatest preference not for the S+, but for a novel stimulus that is slightly more different from the S? than the S+ is. This peak shift phenomenon has been widely reported for vertebrates and has recently been demonstrated for bumblebees and honey bees. To explore the nature of peak shift in invertebrates further, here we examined the properties of peak shift in honey bees trained in a free-flight olfactory learning assay. Hexanal and heptanol were mixed in different ratios to create a continuum of odour stimuli. Bees were trained to artificial flowers such that one odour mixture was rewarded with 2 molar sucrose (S+), and one punished with distasteful quinine (S?). After training, bees were given a non-rewarded preference test with five different mixtures of hexanal and heptanol. Following training bees’ maximal preference was for an odour mixture slightly more distinct from the S? than the trained S+. This effect was not seen if bees were initially trained with two distinct odours, replicating the classic features of peak shift reported for vertebrates. We propose a conceptual model of how peak shift might occur in honey bees. We argue that peak shift does not require any higher level of processing than the known olfactory learning circuitry of the bee brain and suggest that peak shift is a very general feature of discrimination learning.
