Impaired Speech Perception in Poor Readers: Evidence from Hearing and Speech Reading

The performance of 14 poor readers on an audiovisual speech perception task was compared with 14 normal subjects matched on chronological age (CA) and 14 subjects matched on reading age (RA). The task consisted of identifying synthetic speech varying in place of articulation on an acoustic 9-point continuum between /ba/ and /da/ (Massaro & Cohen, 1983). The acoustic speech events were factorially combined with the visual articulation of /ba/, /da/, or none. In addition, the visual-only articulation of /ba/ or /da/ was presented. The results showed that (1) poor readers were less categorical than CA and RA in the identification of the auditory speech events and (2) that they were worse in speech reading. This convergence between the deficits clearly suggests that the auditory speech processing difficulty of poor readers is speech specific and relates to the processing of phonological information.     

Cues to speech segmentation: Evidence from juncture misperceptions and word spotting

The question of whether Dutch listeners rely on the rhythmic characteristics of their native language to segment speech was investigated in three experiments. In Experiment 1, listeners were induced to make missegmentations of continuous speech. The results showed that word boundaries were inserted before strong syllables and deleted before weak syllables. In Experiment 2, listeners were required to spot real CVC or CVCC words (C = consonant, V = vowel) embedded in bisyllabic nonsense strings. For CVCC words, fewer errors were made when the second syllable of the nonsense string was weak rather than strong, whereas for CVC words the effect was reversed. Experiment 3 ruled out an acoustic explanation for this effect. It is argued that these results are in line with an account in which both metrical segmentation and lexical competition play a role.     

Mathematical models for coordinated interpersonal timing in mother-infant interactions in the first year of life

Two mathematical models of social contingency are examined in terms of their development over the first year of life. The interactions of 53 mothers and their infants were recorded at 6 weeks, 4 months, and 12 months. The infants' gazes at 6 weeks, the mothers' vocal behavior at 6 weeks, and the vocal behavior of the mother and infant at 4 and 12 months were automatically coded in terms of four states. The conditional dependence model and the response effects model were computed for each interaction at each age, and the coefficients of the models were examined as a function of age. The relative success of the models as estimates of moment-to-moment contingency as well as their variations with age are discussed.     

Controversies in counseling for mitochondrial conditions

A healthy woman sought preconceptional genetic counseling regarding a family history of a mitochondrial myopathy in her brother and retinitis pigmentosa (RP) in her two maternal aunts. Several questions were raised: (1) What is the likelihood of a familial mitochondrial condition? (2) What molecular tests or prenatal screening can we offer? (3) How would these tests help assess the likelihood of a familial mitochondrial condition? A mitochondrial mutation previously identified in the brother consisted of a heteroplasmic 2.9 kb deletion. We detected this deletion in the peripheral blood of the brother by PCR amplification of the deletion breakpoint, but not in his mother, the consultand, nor in one of the two aunts affected with RP. Although the molecular analysis was encouraging to the consultand, a familial mitochondrial disorder could not be eliminated with certainty. The pros and cons of prenatal testing for mitochondrial disorders are discussed in general, and as specifically related to this family.     

An acceptance-based behavioral intervention for weight loss: a pilot study

On average, participants in behavioral weight-loss interventions lose 8 kilograms (kg) at 6 months, but there is marked variability in outcomes with some participants losing little or no weight. Individuals with difficulties with internal disinhibition (i.e., eating in response to emotions or thoughts) typically lose less weight in such programs and may require an innovative, specialized approach. This pilot study examined the preliminary acceptability and efficacy of a 24-week acceptance-based behavioral intervention for weight loss among overweight and obese adults reporting difficulty with eating in response to emotions and thoughts. Participants were 21 overweight or obese men and women (mean age=52.2±7.6 years; baseline mean body mass index=32.8±3.4). Eighty-six percent completed the 6-month program and a 3-month follow-up assessment. Ratings of program satisfaction averaged 4.9 on a five-point scale. Multilevel modeling analyses indicated participants lost an average of 12.0 kg (SE=1.4) after 6 months of treatment and 12.1 kg (SE=1.9) at 3-month follow-up, thus exceeding the weight losses typically seen in behavioral treatment programs. Decreases in internal disinhibition and weight-related experiential avoidance were found at 6- and 3-months follow-up. Greater decreases in weight-related experiential avoidance were associated with greater weight loss at the end of the program (r=.64, p=.002), suggesting a potential mechanism of action. Although there have been a few preliminary studies using acceptance-based approaches for obesity, this is the first study to specifically target emotional overeaters, a subgroup that might be particularly responsive to this new approach. Our findings provide initial support for the feasibility, efficacy, and acceptability of this approach for this subgroup of participants. Further study with longer follow-up, a more diverse sample, and comparison to a standard behavioral program is clearly warranted.     

Emergent literacy and early writing skills

In the present study, the authors aimed to assess the short- and long-term predictive power of the various components of an emergent literacy model on early writing abilities in a language with a mainly transparent orthography (Italian). Emergent literacy skills were assessed in 72 children (M age = 5.05 years, SD = +/- .03) who were followed longitudinally from preschool to the end of the first grade of primary school. Their early writing abilities (orthographic correctness in writing individual words) and their advanced writing abilities (orthographic correctness in text writing) were tested at the beginning and at the end of the school year. Multiple stepwise and logistic regression analyses were conducted to evaluate the predictive capacities of emergent literacy abilities on early and advanced writing competences. Results show that notational competence is a strong predictor of early writing skills and that phonological competence only has an effect insofar as it is integrated with notational competence. Emergent literacy competences do not significantly predict orthographic errors in advanced text writing. This research allows for reconsideration of the importance of phonological awareness and gives a central role to notational competence in predicting early writing competence.     

Emotions as mind organs

In matters of the mind, the opposition between what is mind-made or inside and natural or outside the mind is bound to misfire. Lindquist et al. build their analysis on a strong contrast between naturalism, which they reject, and psychologism, which they endorse. We challenge this opposition and indicate how adopting psychologism to combat a naturalistic view of emotional mind/brain areas is self-defeating. We briefly develop the alternative view of emotions as mental organs.     

Counseling in Zimbabwe: History,Current Status,and Future Trends

Counseling in Zimbabwe has a long tradition, dating back to pre‐Colonial times. In the modern context, counseling has evolved through the educational and health care sectors. Since the 1990s, Zimbabwean counselors have advocated for professional recognition, a struggle similar to that of counselors in the United States. In this article, the authors provide a historical view of counseling in Zimbabwe, discuss the current status of and future trends in counseling, and make recommendations for the advancement of the profession.
