Investigating distributed practice as a strategy for school students learning mathematics
(2018-09)
Spacing or distributed practice is a prominent learning strategy that is related to the so-called desirable difficulties. With distributed practice, a given learning duration is interrupted by at least one break of variable length. In contrast, with massed practice the same total time is spent learning, but without interruption. There is a rich body of empirical evidence proving the positive effect of distributed practice on the retention of verbal material. Beyond rote memory, however, the empirical grounds regarding ...

Audio-Visual Information Processing across different age groups
(2016-11-14)
People possess different sensory modalities to detect, interpret, and efficiently act upon various events in a complex and dynamic environment (Fetsch, DeAngelis, & Angelaki, 2013). Much empirical work has been done to understand the interplay of modalities (e.g. audio-visual interactions, see Calvert, Spence, & Stein, 2004). On the one hand, integration of multimodal input as a functional principle of the brain enables the versatile and coherent perception of the environment (Lewkowicz & Ghazanfar, 2009). On the ...

Die Wirksamkeit chronischer und akuter sportlicher Aktivität auf die kognitiven Fähigkeiten von Vorschulkindern
(2016-10-26)
Die vorliegende Dissertation untersucht zum einen Zusammenhänge zwischen körperlicher Aktivität, den motorischen Fähigkeiten und den kognitiven Fähigkeiten von 5- bis 6-Jährigen (Studien 1 und 3). Zum anderen wurde für diese Altersgruppe die Wirkung langfristiger (Stu-die 1: N = 81) und einmaliger koordinativer und ausdauerorientierter Interventionen (Studie 2: N = 170; Studie 3: N = 135) auf die kognitiven Fähigkeiten überprüft. Vor und nach den je-weiligen Interventionen wurden die kognitiven Fähigkeiten erhoben ...

Verbal proficiency as fitness indicator: Experimental and comparative research on the evolutionary psychology of language and verbal displays
(2011-10-26)
Summary: Recent research on the evolution of language and verbal displays (e.g., Miller, 1999, 2000a, 2000b, 2002) indicated that language is not only the result of natural selection but serves as a sexually-selected fitness indicator that is an adaptation showing an individual’s suitability as a reproductive mate. Thus, language could be placed within the framework of concepts such as the handicap principle (Zahavi, 1975). There are several reasons for this position: Many linguistic traits are highly heritable ...
