On familiarity deficits in mild cognitive impairment: A reply to Migo and Westerberg

In this brief response to Migo and Westerberg we explain why we think that their criticism of our previous research showing familiarity deficits in mild cognitive impairment patients (MCI) is not sound. More concretely, we have replicated the effect several times previously, and we justify statistically the fact that in the previous paper we had to combine two MCI samples to demonstrate a reliable familiarity deficit. We note that there are several studies showing conflicting results. However, although the basis for these discrepancies remains uncertain, a new report has replicated the presence of deficits in familiarity, and more importantly, demonstrated its correlation with structural imaging biomarkers of Alzheimer’s disease.     

Los modelos del proceso de la escritura

Resumen

El presente articulo trata de ofrecer una visión general de cuál es el estado en que se encuentran las teorías sobre el proceso de escritura. Para ello se expone, en primer lugar, cuál ha sido la evolución de los supuestos que subyacen a los modelos de escritura, modelos que pueden clasificarse en tres grandes grupos: los modelos de traducción, los modelos de etapas y los actuales modelos cognitivos. En segundo lugar, se señalan algunos factores que han contribuido a la aparición de estos últimos, así como algunos de sus objetivos y requisitos. A continuación se expone el modelo de Flower y Hayes (1979, 1980, 1981 a y b) como un ejemplo prototípico de esta orientación. Por último, se ofrecen una serie de conclusiones respecto a la evolución de los modelos, respecto a las características comunes generales que comparten los modelos cognitivos y respecto a las tendencias actuales en la construcción de dichas teorías.     

How do therapists ally with adolescents in family therapy? An examination of relational control communication in early sessions

Sequential analyses examined associations between the working alliance and therapist-adolescent communication patterns in 10 Spanish cases of brief conjoint family therapy. Early sessions with strong versus problematic alliances, rated by observers, were selected for coding of relational control communication patterns. No differences were found in the frequency of exchanges, but competitive responding by the therapists (reflecting an interpersonal struggle for control) was significantly more likely in problematic alliance sessions than in strong alliance sessions. Cases in which the adolescent's alliance with the therapist remained positive from Session 1 as compared with Session 3 showed a decrease in the likelihood of competitive symmetry. Notably, when the quality of the alliance deteriorated over time, the therapists were increasingly more likely to respond to the adolescents' domineering messages in a competitive manner. Results underscore the need to avoid competitive responding in order to ally with adolescents in conjoint family treatment.     

Weighting of vowel cues explains patterns of word–object associative learning

Previous research has demonstrated that infants under 17 months have difficulty learning novel words in the laboratory when the words differ by only one consonant sound, irrespective of the magnitude of that difference. The current study explored whether 15‐month‐old infants can learn novel words that differ in only one vowel sound. The rich acoustic/phonetic properties of vowels allow for a detailed analysis of the contribution of acoustic/phonetic cues to infants’ performance with similar‐sounding words. Infants succeeded with the vowel pair /i/–/I/, but failed with vowel pairs /i/–/u/ and /I/–/u/. These results suggest that infants initially use the most salient acoustic cues for vowels and that this staged use of acoustic cues both predicts and explains why infants can learn some words that differ in only a single vowel.     

Assessing short summaries with human judgments procedure and latent semantic analysis in narrative and expository texts

In the present study, we tested a computer-based procedure for assessing very concise summaries (50 words long) of two types of text (narrative and expository) using latent semantic analysis (LSA) in comparison with the judgments of four human experts. LSA was used to estimate semantic similarity using six different methods: four holistic (summary-text, summary-summaries, summary-expert summaries, and pregraded-ungraded summary) and two componential (summary-sentence text and summary-main sentence text). A total of 390 Spanish middle and high school students (14–16 years old) and six experts read a narrative or expository text and later summarized it. The results support the viability of developing a computerized assessment tool using human judgments and LSA, although the correlation between human judgments and LSA was higher in the narrative text than in the expository, and LSA correlated more with human content ratings than with human coherence ratings. Finally, the holistic methods were found to be more reliable than the componential methods analyzed in this study.     

“Mummy,keep it steady”: phonetic variation shapes word learning at 15 and 17 months

Fifteen‐month‐olds have difficulty detecting differences between novel words differing in a single vowel. Previous work showed that Australian English (AusE) infants habituated to the word‐object pair DEET detected an auditory switch to DIT and DOOT in Canadian English (CanE) but not in their native AusE (Escudero et al., 2014 ). The authors speculated that this may be because the vowel inherent spectral change variation (VISC) in AusE DEET is larger than in CanE DEET. We investigated whether VISC leads to difficulty in encoding phonetic detail during early word learning, and whether this difficulty dissipates with age. In Experiment 1, we familiarized AusE‐learning 15‐month‐olds to AusE DIT, which contains smaller VISC than AusE DEET. Unlike infants familiarized with AusE DEET (Escudero et al., 2014 ), infants detected a switch to DEET and DOOT. In Experiment 2, we familiarized AusE‐learning 17‐month‐olds to AusE DEET. This time, infants detected a switch to DOOT, and marginally detected a switch to DIT. Our acoustic analysis showed that AusE DEET and DOOT are differentiated by the second vowel formant, while DEET and DIT can only be distinguished by their changing dynamic properties throughout the vowel trajectory. Thus, by 17 months, AusE infants can encode highly dynamic acoustic properties, enabling them to learn the novel vowel minimal pairs that are difficult at 15 months. These findings suggest that the development of word learning is shaped by the phonetic properties of the specific word minimal pair.     

Alliance and Treatment Outcome in Family-Involved Treatment for Youth Problems: A Three-Level Meta-analysis

Alliance has been shown to predict treatment outcome in family-involved treatment for youth problems in several studies. However, meta-analytic research on alliance in family-involved treatment is scarce, and to date, no meta-analytic study on the alliance–outcome association in this field has paid attention to moderating variables. We included 28 studies reporting on the alliance–outcome association in 21 independent study samples of families receiving family-involved treatment for youth problems (N = 2126 families, M age youth ranging from 10.6 to 16.1). We performed three multilevel meta-analyses of the associations between three types of alliance processes and treatment outcome, and of several moderator variables. The quality of the alliance was significantly associated with treatment outcome (r = .183, p < .001). Correlations were significantly stronger when alliance scores of different measurement moments were averaged or added, when families were help-seeking rather than receiving mandated care and when studies included younger children. The correlation between alliance improvement and treatment outcome just failed to reached significance (r = .281, p = .067), and no significant correlation was found between split alliances and treatment outcome (r = .106, p = .343). However, the number of included studies reporting on alliance change scores or split alliances was small. Our findings demonstrate that alliance plays a small but significant role in the effectiveness of family-involved treatment. Future research should focus on investigating the more complex systemic aspects of alliance to gain fuller understanding of the dynamic role of alliance in working with families.     

Cross‐Situational Learning of Minimal Word Pairs

Cross‐situational statistical learning of words involves tracking co‐occurrences of auditory words and objects across time to infer word‐referent mappings. Previous research has demonstrated that learners can infer referents across sets of very phonologically distinct words (e.g., WUG, DAX), but it remains unknown whether learners can encode fine phonological differences during cross‐situational statistical learning. This study examined learners’ cross‐situational statistical learning of minimal pairs that differed on one consonant segment (e.g., BON–TON), minimal pairs that differed on one vowel segment (e.g., DEET–DIT), and non‐minimal pairs that differed on two or three segments (e.g., BON–DEET). Learners performed above chance for all pairs, but performed worse on vowel minimal pairs than on consonant minimal pairs or non‐minimal pairs. These findings demonstrate that learners can encode fine phonetic detail while tracking word‐referent co‐occurrence probabilities, but they suggest that phonological encoding may be weaker for vowels than for consonants.

Detection of counting pseudoerrors: What helps children accept them?

This study examines children's comprehension of non‐essential counting features (conventional rules). The objective of the study was to determine whether the presence or absence of cardinal values in pseudoerrors and the type of conventional rule violated affects children's performance. A detection task with pseudoerrors was presented through a computer game to 146 primary school children in grades 2 through 4. The same pseudoerrors were presented both with and without cardinal values; the pseudoerrors violated conventional rules of spatial adjacency, temporal adjacency, spatial–temporal adjacency, and left‐to‐right direction. Half of the participants within each age group were randomly assigned to an experimental condition that included pseudoerrors with a cardinal value, and the other half were assigned to a condition that included pseudoerrors without a cardinal value. The results show that when presented with a cardinal value, children more easily recognize the optional nature of non‐essential counting features. Likewise, the type of conventional rule transgressed significantly affected the children's acceptance of pseudoerrors as valid counts. Participants penalized breaches of temporal and spatial–temporal adjacency to a greater degree than breaches of spatial adjacency and left‐to‐right direction.
