In the Netherlands the anti-Flynn effect is a Jensen effect

In this study, 63 observations of secular IQ changes (both Flynn and anti-Flynn effects) are collected from three demographically diverse studies of the Dutch population for the period 1975–2005 (representing the 1950–1990 birth cohorts), along with data on g loadings and subtest reliabilities. The method of correlated vectors is used to explore the association between Flynn and anti-Flynn effect magnitudes, both independently and together, and the g loadings of subtests. Despite a positive vector correlation the Flynn effects are not associated with the Jensen effect (r = .307, ns, N = 36), however the anti-Flynn effects are (r = .406, P = .05, N = 27). Combined, the vector correlation becomes negative but non-significant (r = −.111, ns, N = 63). Declines due to the anti-Flynn effect are estimated at −4.515 points per decade, whereas gains due to the Flynn effect are estimated at 2.175 points per decade. The N-weighted net of these is a loss of −1.350 points per decade, suggesting an overall tendency towards decreasing IQ in the Netherlands with respect to these cohorts. The Jensen effect on the anti-Flynn effect suggests that it may be related to bio-demographic changes within the Netherlands which have reduced ‘genetic-g’, despite the presence of large, parallel gains on subtests that may be relatively more sensitive to cultural-environmental improvements.     

择偶与人类嗓音

本文对择偶与人类嗓音之间的关系进行了深入分析。首先, 人类具有普遍的异性嗓音偏好：男性偏爱高音调的女性嗓音, 女性偏爱低音调的男性嗓音, 这种普遍偏好受到一系列跟自身婚配价值有关的因素的调节。其次, 人类的嗓音偏好跟嗓音背后的进化意义密切关联：女性化嗓音是女性生育力的线索, 而男性化嗓音是男性好基因和好资源的线索。而且, 富有吸引力的男性嗓音和女性嗓音能够预测个体的性行为和繁殖成功。再次, 富有有吸引力的人类嗓音影响个体的社会认知, 对亲密关系的维系也会带来消极影响。最后, 我们探讨了未来研究的若干方向：研究基频之外的其他嗓音参数, 探讨嗓音偏好的性选择机制、特殊群体的嗓音偏好, 以及嗓音偏好与其他认知过程的关系。     

Co-occurrence frequency evaluated with large language corpora boosts semantic priming effects

In recent decades, many computational techniques have been developed to analyse the contextual usage of words in large language corpora. The present study examined whether the co-occurrence frequency obtained from large language corpora might boost purely semantic priming effects. Two experiments were conducted: one with conscious semantic priming, the other with subliminal semantic priming. Both experiments contrasted three semantic priming contexts: an unrelated priming context and two related priming contexts with word pairs that are semantically related and that co-occur either frequently or infrequently. In the conscious priming presentation (166-ms stimulus-onset asynchrony, SOA), a semantic priming effect was recorded in both related priming contexts, which was greater with higher co-occurrence frequency. In the subliminal priming presentation (66-ms SOA), no significant priming effect was shown, regardless of the related priming context. These results show that co-occurrence frequency boosts pure semantic priming effects and are discussed with reference to models of semantic network.     

Age of acquisition ratings score better on criterion validity than frequency trajectory or ratings “corrected” for frequency

From the very first studies on the effect of age of acquisition (AoA) on word processing, researchers have validated their AoA ratings by correlating them with other, more objective indices of the age at which children know words. Still, the ratings have been questioned, and alternative measures have been proposed. Two of these are differences in word frequency between language directed at young children and language directed at older children (frequency trajectory) and AoA ratings corrected for word frequency. Surprisingly, the criterion validity of these alternative measures has never been established, partly because one of the validation criteria (the age at which children are able to name pictures) has been questioned. In the present study, four databases are used that aimed to establish the order of English word acquisition, going from the very first words learned to words taught in secondary education. The criteria for word knowledge included word production, multiple-choice questions about the meaning of the words, and teacher judgments about when words should be taught in the school curriculum. For all databases, the frequency trajectory correlated substantially less with the criterion than AoA ratings. For all but one, the same was true for AoA ratings “corrected” for other variables. On the basis of these findings, researchers should be cautious interpreting null effects with the “improved” variables as evidence against a genuine AoA effect.     

Extrapolating human judgments from skip-gram vector representations of word meaning

There is a growing body of research in psychology that attempts to extrapolate human lexical judgments from computational models of semantics. This research can be used to help develop comprehensive norm sets for experimental research, it has applications to large-scale statistical modelling of lexical access and has broad value within natural language processing and sentiment analysis. However, the value of extrapolated human judgments has recently been questioned within psychological research. Of primary concern is the fact that extrapolated judgments may not share the same pattern of statistical relationship with lexical and semantic variables as do actual human judgments; often the error component in extrapolated judgments is not psychologically inert, making such judgments problematic to use for psychological research. We present a new methodology for extrapolating human judgments that partially addresses prior concerns of validity. We use this methodology to extrapolate human judgments of valence, arousal, dominance, and concreteness for 78,286 words. We also provide resources for users to extrapolate these human judgments for three million English words and short phrases. Applications for large sets of extrapolated human judgments are demonstrated and discussed.     

How does information from low and high spatial frequencies interact during scene categorization?

Current models of visual perception suggest that, during scene categorization, low spatial frequencies (LSF) are rapidly processed and activate plausible interpretations of visual input. This coarse analysis would be used to guide subsequent processing of high spatial frequencies (HSF). The present study aimed to further examine how information from LSF and HSF interact and influence each other during scene categorization. In a first experimental session, participants had to categorize LSF and HSF filtered scenes belonging to two different semantic categories (artificial vs. natural). In a second experimental session, we used hybrid scenes as stimuli made by combining LSF and HSF from two different scenes which were semantically similar or dissimilar. Half of the participants categorized LSF scenes in hybrids, and the other half categorized HSF scenes in hybrids. Stimuli were presented for 30 or 100?ms. Session 1 results showed better performance for LSF than HSF scene categorization. Session 2 scene categorization was faster when participants attended and categorized LSF than HSF scene in hybrids. The semantic interference of a semantically dissimilar HSF scene on LSF scene categorization was greater than the semantic interference of a semantically dissimilar LSF scene on HSF scene categorization, irrespective of exposure duration. These results suggest a LSF advantage for scene categorization, and highlight the prominent role of HSF information when there is uncertainty about the visual stimulus, in order to disentangle between alternative interpretations.     

Trouble articulating the right words: Evidence for a response‐exclusion account of distraction during semantic fluency

It is widely held that single‐word lexical access is a competitive process, a view based largely on the observation that naming a picture is slowed in the presence of a distractor‐word. However, problematic for this view is that a low‐frequency distractor‐word slows the naming of a picture more than does a high‐frequency word. This supports an alternative, response‐exclusion, account in which a distractor‐word interferes because it must be excluded from an articulatory output buffer before the right word can be articulated (the picture name): A high, compared to low, frequency word accesses the buffer more quickly and, as such, can also be excluded more quickly. Here we studied the respective roles of competition and response‐exclusion for the first time in the context of semantic verbal fluency, a setting requiring the accessing of, and production of, multiple words from long‐term memory in response to a single semantic cue. We show that disruption to semantic fluency by a sequence of to‐be‐ignored spoken distractors is also greater when those distractors are low in frequency, thereby extending the explanatory compass of the response‐exclusion account to a multiple‐word production setting and casting further doubt on the lexical‐selection‐by‐competition view. The results can be understood as reflecting the contribution of speech output processes to semantic fluency.

Attentional blink for acronyms: Effects of familiarity and pre‐exposure

Seventy‐two university students participated in one of two experiments in the rapid serial visual presentation (RSVP) task. Distractors were four‐letter non‐words, the first target (T1) was a four‐letter word, and the second target (T2) was a two‐four‐letter acronym that followed T1 at lags of 2, 3 and 5 items (Experiment 1) or lags of 3 and 5 items (Experiment 2). Familiar acronyms were identified better than unfamiliar acronyms. One pre‐exposure of acronyms in a rating task improved RSVP accuracy for familiar acronyms only (Experiments 1 and 2), whereas three pre‐exposures produced a benefit for unfamiliar acronyms and no significant additional benefit for familiar acronyms (Experiment 2). Thus a pre‐existing unitised memory representation, and a relatively recent access of this representation, enhanced target identification. The effects of pre‐exposure were more consistent with resource depletion than attentional filtering accounts of the attentional blink.     

词频、易接近性和词表序列成分对近因效应影响的实验研究

本研究目的探讨词频、易接近性和词表序列成分对近因效应的影响及其原因。两个实验以不同词频和不同易接近性的中文词为材料,运用直接自由回忆程序和操纵词表的组成成分,探讨近因效应的特点。实验结果表明：词频对近因效应的作用受词表序列成分的影响,对于纯的词表,高频词回忆的比例比低频词更高,对于混合词表,低频词回忆的比例比高频词更高,但是词的易接近性不影响近因效应且不受词表序列成分影响。文章最后对近因效应的性质进行了讨论。
