Roots, stems, and the universality of lexical representations: evidence from Hebrew

Is the structure of lexical representations universal, or do languages vary in the fundamental ways in which they represent lexical information? Here, we consider a touchstone case: whether Semitic languages require a special morpheme, the consonantal root. In so doing, we explore a well-known constraint on the location of identical consonants that has often been used as motivation for root representations in Semitic languages: Identical consonants frequently occur at the end of putative roots (e.g., skk), but rarely occur in their beginning (e.g., ssk). Although this restriction has traditionally been stated over roots, an alternative account could be stated over stems, a representational entity that is found more widely across the world's languages. To test this possibility, we investigate the acceptability of a single set of roots, manifesting identity initially, finally or not at all (e.g., ssk versus skk versus rmk) across two nominal paradigms: CéCeC (a paradigm in which identical consonants are rare) and CiCúC (a paradigm in which identical consonants are frequent). If Semitic lexical representations consist of roots only, then similar restrictions on consonant co-occurrence should be observed in the two paradigms. Conversely, if speakers store stems, then the restriction on consonant co-occurrence might be modulated by the properties of the nominal paradigm (be it by means of statistical properties or their grammatical sources). Findings from rating and lexical decision experiments with both visual and auditory stimuli support the stem hypothesis: compared to controls (e.g., rmk), forms with identical consonants (e.g., ssk, skk) are less acceptable in the CéCeC than in the CiCúC paradigm. Although our results do not falsify root-based accounts, they strongly raise the possibility that stems could account for the observed restriction on consonantal identity. As such, our results raise fresh challenge to the notion that different languages require distinct sets of representational resources.     

The role of Hebrew letter names in early literacy: the case of multiphonemic acrophonic names

English-speaking children spell letters correctly more often when the letters' names are heard in the word (e.g., B in beach vs. bone). Hebrew letter names have been claimed to be less useful in this regard. In Study 1, kindergartners were asked to report and spell initial and final letters in Hebrew words that included full (CVC), partial (CV), and phonemic (C) cues derived from these letter names (e.g., kaftor, kartis, kibepsilonl, spelled with /kaf/). Correct and biased responses increased with length of congruent and incongruent cues, respectively. In Study 2, preschoolers and kindergartners were asked to report initial letters with monosyllabic or disyllabic names (e.g., /kaf/ or /samepsilonx/, respectively) that included the cues described above. Correct responses increased with cue length; the effect was stronger with monosyllabic letter names than with disyllabic letter names, probably because the cue covered a larger ratio of the letter name. Phonological awareness was linked to use of letter names.     

Automatic Emotion Regulation

How do people effectively regulate their emotional reactions? Why are some people better at this than others? Most prior research has addressed these questions by focusing on deliberate forms of emotion regulation. We argue that this focus has left out an important aspect of emotion regulation, namely, automatic emotion regulation (AER). Our review of the behavioral literature suggests that AER is pervasive in everyday life, and has far‐reaching consequences for individuals’ emotions. However, the behavioral literature has yet to address the mechanisms underlying the observed effects. Because it is difficult to directly measure the processes involved in AER, evidence from neuroscientific studies is particularly helpful in addressing these questions. Our review of the neuroscientific literature suggests distinct neural bases for different types of AER, which provides important clues about the cognitive and behavioral processes that might be involved in AER.     

Perinatal positive parenting: Three case reviews

Important insights into the nature of the Perinatal Positive Parenting program can be gained through case reviews by the volunteer parents regarding their experiences with the program. Some information about the impact of the program on the new parent involved can only be captured in this way. This is also true of the considerable positive impact the program has had on the volunteers themselves. In this article three of the Perinatal Positive Parenting program volunteers outline these dimensions in brief case reviews. Bibliographic vignettes of the three volunteers are also provided.     

The effects of photographs and event plausibility in creating false beliefs

Recent studies have shown that using photographs as memory retrieval aids can significantly increase the likelihood of false memories. The current study further investigated this effect by examining the interactive effects of photographs and event plausibility in developing false beliefs. At Time 1 and two weeks later at Time 2, participants rated 20 events on the Life Events Inventory (LEI) as to whether each occurred to them in childhood. One week after Time 1, participants were told that two target events were plausible and two were implausible. They then used event-related photographs to visualize one plausible and one implausible event. Occurrence ratings significantly increased from Time 1 to Time 2 for plausible events in the photo condition. These results suggest that the use of photographs as a memory enhancing technique is unlikely to cause false memories for events that are not perceived personally plausible.     

Repeated checking causes distrust in memory but not in attention and perception

Repeated checking to reduce memory distrust seems to be counterproductive: it increases memory distrust. Obsessive-compulsive (OC) patients tend to be uncertain about other cognitive domains as well, like attention and perception. In an experiment with 70 healthy participants, we tested whether perseverative checking induces distrust not only in memory, but also in attention and perception. Participants were administered a computer task in which they had to activate, deactivate, and check threat-irrelevant stimuli, and rate their confidence in memory, attention, and perception in a pre-test and post-test. In between these tests, the relevant checking group performed 20 checks of the same stimuli used in the pre- and post-test. The irrelevant checking group performed 20 checks of different stimuli. Although memory accuracy improved in both groups, repeated checking reduced confidence in memory, vividness, and detail in the relevant checking group, but not in the irrelevant checking group. A trend was found towards a decline in attentional confidence in the relevant checking group only. Perception was not affected by repetitive checking. A replication study revealed similar results of relevant checking on meta-memory, however, the trend for attentional distrust was not confirmed. The results suggest that perseveration may be domain specific, i.e., only the cognitive processes that are subject to perseveration are affected.     

Remuneration differences in the emerging economies of China and India

Emerging economies by definition tend to be less dependent on expatriate skills and labour than lower-income countries, yet remuneration (pay plus benefits) differences between expatriate and local workers persist in them to some degree. According to relative deprivation theory, economic development paradoxically elevates the salience of relatively small gaps in remuneration. We therefore expected workers to report injustice and demotivation regarding relative remuneration, despite the closing of remuneration gaps between expatriate and local workers due to the economic development of recent years. To explore that possibility, 482 skilled professionals from a variety of sectors and organizations in two emerging economies, India (n = 233, response rate = 54%) and China (n = 249, response rate = 58%), participated in the research. International salaries were greater than local salaries by a factor of 2.73:1 in India and 1.90:1 in China; these mean ratios bordered on intolerable in the India sample and were largely tolerable among the sample from China. In both countries, differently remunerated workers differed in their justice cognitions and their demotivation, with lowered motivation and fewer justice cognitions in the locally salaried, local workers. These differences were however more statistically significant between people working in India than in China. Insofar as the motivational and justice gaps persisted, the findings support relative deprivation theory. Insofar as the same gaps appear to be sharper in the country with the higher-not lower-mean remuneration differential, they do not. An in-country workshop with local experts who interpreted the findings (in India), and content analysis of the participants' recommendations (in China) jointly recommended linking remuneration to (i) workplace performance instead of (ii) economy-of-origin, to help promote (iii) fairness.     

Modelling non‐normal data: The relationship between the skew‐normal factor model and the quadratic factor model

Maximum likelihood estimation of the linear factor model for continuous items assumes normally distributed item scores. We consider deviations from normality by means of a skew‐normally distributed factor model or a quadratic factor model. We show that the item distributions under a skew‐normal factor are equivalent to those under a quadratic model up to third‐order moments. The reverse only holds if the quadratic loadings are equal to each other and within certain bounds. We illustrate that observed data which follow any skew‐normal factor model can be so well approximated with the quadratic factor model that the models are empirically indistinguishable, and that the reverse does not hold in general. The choice between the two models to account for deviations of normality is illustrated by an empirical example from clinical psychology.     

Relapse/Recurrence Prevention in Major Depressive Disorder: 26-Month Follow-Up of Mindfulness-Based Cognitive Therapy Versus an Active Control

We conducted a 26-month follow-up of a previously reported 12-month study that compared mindfulness-based cognitive therapy (MBCT) to a rigorous active control condition (ACC) for depressive relapse/recurrence prevention and improvements in depressive symptoms and life satisfaction. Participants in remission from major depression were randomized to an 8-week MBCT group (n = 46) or the ACC (n = 46). Outcomes were assessed at baseline; postintervention; and 6, 12, and 26 months. Intention-to-treat analyses indicated no differences between groups for any outcome over the 26-month follow-up. Time to relapse results (MBCT vs. ACC) indicated a hazard ratio = .82, 95% CI [.34, 1.99]. Relapse rates were 47.8% for MBCT and 50.0% for ACC. Piecewise analyses indicated that steeper declines in depressive symptoms in the MBCT vs. the ACC group from postintervention to 12 months were not maintained after 12 months. Both groups experienced a marginally significant rebound of depressive symptoms after 12 months but were still improved at 26 months compared to baseline (b = –4.12, p <= .008). Results for life satisfaction were similar. In sum, over a 26-month follow-up, MBCT was no more effective for preventing depression relapse/recurrence, reducing depressive symptoms, or improving life satisfaction than a rigorous ACC. Based on epidemiological data and evidence from prior depression prevention trials, we discuss the possibility that both MBCT and ACC confer equal therapeutic benefit. Future studies that include treatment as usual (TAU) control conditions are needed to confirm this possibility and to rule out the potential role of time-related effects. Overall findings underscore the importance of comparing MBCT to TAU as well as to ACCs.
