Cross-linguistic differences in gender congruency effects: Evidence from meta-analyses

It has been proposed that the order in which words are prepared for production depends on the speaker's language. When producing the translation equivalent of the small cat, speakers of German or Dutch select the gender-marked determiner at a relatively early stage of production. Speakers of French or Italian postpone the encoding of a determiner or adjective until the phonological form of the noun is available. Hence, even though the words are produced in the same order (e.g., die kleine Katze in German, le petit chat in French), they are not planned in the same order and might require different amounts of advanced planning prior to production onset. This distinction between early and late selection languages was proposed to account for the observation that speakers of Germanic and Slavic languages, but not of Romance languages, are slower to name pictures in the context of a distractor word of a different gender. Meta-analyses are conducted to provide the first direct test of this cross-linguistic difference and to test a prediction of the late selection hypothesis. They confirm the existence of the gender congruency effect in German/Slavic languages and its absence in Romance languages when target and distractor words are presented simultaneously. They do not allow confirming the hypothesis that in the latter languages, a similar effect emerges when the presentation of the distractor is delayed. Overall, these analyses confirm the cross-linguistic difference but show that the evidence available to date is not sufficient to confirm or reject the late selection hypothesis as an explanation of this difference. We highlight specific directions for future research.

When words collide: Bayesian meta-analyses of distractor and target properties in the picture-word interference paradigm

In the picture-word interference paradigm, participants name pictures while ignoring a written or spoken distractor word. Naming times to the pictures are slowed down by the presence of the distractor word. Various properties of the distractor modulate this slow down, for example naming times are shorter with frequent vs. infrequent distractors. Building on this line of research, the present study investigates in more detail the impact of distractor and target word properties on picture naming times. We report the results of several Bayesian meta-analyses, based on 35 datasets. The aim of the first analysis was to obtain an estimation of the size of the distractor frequency effect, and of its precision, in typical picture-word interference experiments where this variable is not manipulated. The analysis shows that a one-unit increase in log frequency results in response times to the pictures decreasing by about 4ms (95% Credible Interval: [-6, -2]). With the second and third analyses, we show that after accounting for the effect of frequency, two variables known to influence processing times in visual word processing tasks also influence picture naming times: distractor length and orthographic neighborhood. Finally, we found that distractor word frequency and target word frequency interact; the effect of distractor frequency decreases as the frequency of the target word increases. We discuss the theoretical and methodological implications of these findings, as well as the importance of obtaining high-precision estimates of experimental effects.

Picture-word interference in language production studies: Exploring the roles of attention and processing times

The picture-word interference paradigm (participants name target pictures while ignoring distractor words) is often used to model the planning processes involved in word production. The participants' naming times are delayed in the presence of a distractor (general interference). The size of this effect depends on the relationship between the target and distractor words. Distractors of the same semantic category create more interference (semantic interference), distractors overlapping in phonology create less interference (phonological facilitation). The present study examines the relationships between these experimental effects, processing times, and attention in order to better understand the cognitive processes underlying participants' behavior in this paradigm. Participants named pictures with a superimposed line of Xs, semantically related distractors, phonologically related distractors, or unrelated distractors. General interference, semantic interference, and phonological facilitation effects are replicated. Distributional analyses reveal that general and semantic interference effects increase with naming times, while phonological facilitation decreases. The phonological facilitation and semantic interference effects are found to depend on the synchronicity in processing times between the planning of the picture's name and the processing of the distractor word. Finally, EEG power in the alpha band before stimulus onset varied with the position of the trial in the experiment and with repetition but did not predict the size of interference or facilitation effects. Taken together, these results suggest that experimental effects in the picture-word interference paradigm depend on processing times to both the target word and distractor word and that distributional patterns could party reflect this dependency.

Behavioral and EEG evidence for inter-individual variability in late encoding stages of word production

Individuals differ in the time it takes to produce words when naming a picture. However, it is unknown whether this inter-individual variability emerges in earlier stages of word production (e.g., lexical selection) or later stages (e.g., articulation). The current study measured participants' (N = 45) naming latencies and continuous EEG in a picture-word-interference task, as well as naming latencies in a delayed naming task. The inter-individual variability in naming latencies in immediate naming was not larger than the variability in the delayed task. Thus, a large part of the variability in immediate naming seems to originate in relatively late stages of word production. This interpretation was complemented by the EEG data: Differences between relatively fast vs. slow speakers were seen in response-aligned analyses in a time window close to the vocal response. Finally, we show that inter-individual variability can influence EEG results at the group level.
